Static GK is the largest part of General Studies in every state exam, and most of it is national. Indian polity, history and the national movement, geography of India, the Indian economy and general science appear in the syllabus of UPPSC PCS and PET, BPSC and BSSC, RPSC and RSSB, MPPSC and MPESB, HPSC and HSSC, and DSSSB and Delhi Police. The level changes from exam to exam. PET sets its subjects at NCERT secondary and senior secondary level, BSSC asks matric-level science, and RPSC sets the RAS Prelims at Bachelor's degree standard. This page brings together GK24's topic-wise GK notes tagged for state exams. Each note covers one topic in English and Hindi, as short facts and tables that can be revised in one sitting, and ends with multiple-choice questions and explanations. Start with Polity, History and Geography, then move to the Economy and Science. GK24 does not have state GK sections. As guidance, use these notes for the national part and prepare your state's history, geography, culture, economy and schemes from state board textbooks, the state budget and economic survey, and the commission's past papers. After each note, take its topic quiz and mark what you got wrong.
What is the SI unit of radioactivity?
One becquerel is one disintegration per second, and it is the SI unit of the activity of a radioactive source, named after the discoverer of radioactivity.
Read the full explanation →The energy radiated by the Sun is produced mainly by which process?
In the core of the Sun, at temperatures of millions of degrees, hydrogen nuclei fuse in stages to form helium, and the small amount of mass lost in the process appears as energy according to Einstein's mass-energy relation.
Read the full explanation →Control rods used to regulate the rate of a nuclear chain reaction are commonly made of which materials?
Both absorb neutrons strongly, so pushing the rods into the core removes neutrons and slows the chain reaction, while withdrawing them allows the reaction to build up; this is how the power of a reactor is controlled and how it is shut down.
Read the full explanation →In a nuclear reactor, heavy water is used mainly for which purpose?
Heavy water, in which the hydrogen of ordinary water is replaced by deuterium, slows the fast neutrons released in fission to low speeds at which they are far more likely to split further uranium nuclei, and it absorbs very few neutrons in doing so, which is why Indian pressurised heavy…
Read the full explanation →Which of the following radiations has the greatest penetrating power?
Gamma radiation is electromagnetic, carries no charge and no rest mass, and therefore passes through matter far more easily than charged particles; thick lead or concrete is needed to reduce it.
Read the full explanation →When a nucleus emits an alpha particle, how do its mass number and atomic number change?
An alpha particle takes away two protons and two neutrons, so the parent loses four units of mass number and two units of atomic number and becomes an element two places earlier in the periodic table; uranium-238, for instance, becomes thorium-234.
Read the full explanation →An alpha particle is identical to the nucleus of which atom?
An alpha particle consists of two protons and two neutrons bound together, which is exactly the nucleus of a helium-4 atom, so it carries a charge of plus two and a mass number of four.
Read the full explanation →Radioactivity was discovered by which scientist?
In 1896 Becquerel found that a uranium salt kept in the dark fogged a wrapped photographic plate, which showed that the salt emitted its own penetrating radiation without being exposed to light.
Read the full explanation →A hydrogen bomb creates devastating explosion because of
A hydrogen bomb, also called a thermonuclear bomb, works in two steps. A fission explosion of uranium or plutonium produces the temperature of millions of degrees needed to force light nuclei together, and the fusion of those nuclei then releases far more energy than the fission stage alone.
Read the full explanation →Which radioactive isotope has a half-life of 5770 years, which is commonly used to estimate the age of organic materials such as paper and parchment?
Carbon-14 is the radioactive isotope of carbon used for radiocarbon dating, and its half-life is close to 5,700 years, which is the figure quoted in the question.
Read the full explanation →Concessoc 41 SAS, the acquirer of Vishavari Tollway and nine road SPVs, is ultimately controlled by which company?
The acquirer is a company incorporated under the laws of France and is ultimately controlled by VINCI S.A. through VINCI Highways and VINCI Concessions.
Read the full explanation →What equity stake does JSW Projects currently hold in BMM Ispat Limited?
JSW Projects Limited, an unlisted company of the JSW Group based in Mumbai, holds that share of the equity in BMM Ispat Limited at present, and the proposed combination is meant to convert this majority interest into full ownership by amalgamating BMM into JSW Steel Limited.
Read the full explanation →Which regulator approved the proposed combination amalgamating BMM Ispat into JSW Steel?
It is the statutory authority that examines proposed combinations, meaning mergers, amalgamations and acquisitions above the prescribed thresholds, to see whether they would cause an appreciable adverse effect on competition in India, and it cleared this internal restructuring of the JSW Group along with three other combinations the same day.
Read the full explanation →Who is the Union Minister for Communications who took part in the interaction with the GSMA Board?
He has been leading India engagement with the global telecom ecosystem on next-generation connectivity, and at Mobile World Congress in Barcelona he addressed the GSMA Ministerial Programme on making connectivity more affordable, inclusive and future-ready.
Read the full explanation →Which edition of the India Mobile Congress is India preparing to host in New Delhi?
The interaction with the GSMA Board came as India prepared to host the tenth edition of India Mobile Congress in New Delhi, an event that gathers global technology and telecom leaders.
Read the full explanation →Where did the Prime Minister interact with the Board members of the GSMA?
The Prime Minister held the interaction with Board members of the Global System for Mobile Communications Association at Seva Teerth, ahead of India Mobile Congress.
Read the full explanation →By when must the bankers committees submit their action-taken report to the Department of Financial Services?
The directions ask convenors of State Level Bankers Committees and Union Territory Level Bankers Committees to share the Scheduled Caste beneficiary information with the Commission regularly and to send an action-taken report to the Department of Financial Services by that date, setting out how far the data is available and…
Read the full explanation →Under which constitutional provision is the National Commission for Scheduled Castes required to evaluate the socio-economic development of Scheduled Castes?
The Commission told the Department of Financial Services that the absence of Scheduled Caste beneficiary figures in bankers committee reports was hindering the constitutional mandate this clause gives it, namely to evaluate the progress of socio-economic development of the Scheduled Castes.
Read the full explanation →Which department has directed bankers committees to report Scheduled Caste beneficiary data scheme-wise and bank-wise?
It is the department of the Finance Ministry that deals with banks, insurance and the financial inclusion schemes, and it is the body that issued the directions to convenors of State Level Bankers Committees and their Union Territory counterparts after the National Commission for Scheduled Castes raised the gap.
