Static GK makes up most of the General Awareness syllabus of RRB JE, and General Science adds a larger block of its own. CEN 04/2026 lists Indian geography, the culture and history of India including the freedom struggle, Indian Polity and Constitution, the Indian Economy and environmental issues concerning India and the world. In CBT-1 these share 15 questions with current affairs, while General Science, which the CEN defines as Physics, Chemistry and Life Sciences up to the 10th Standard CBSE syllabus, has 30 questions of its own. CBT-2 repeats the General Awareness syllabus in 15 questions and adds 15 on Physics and Chemistry, 10 on Basics of Computers and Applications and 10 on Basics of Environment and Pollution Control. This page holds GK24's topic-wise GK notes for RRB JE: Polity, History, Geography, the Economy, Art and Culture, Environment and Ecology, General Science and Computer basics. Each note is a set of short facts and tables in English and Hindi that can be revised in one sitting. Read one topic, solve its quiz and previous-year questions, and return to it a week later. With 15 General Awareness questions spread over eight areas, breadth matters more than depth, while General Science rewards thorough revision of Class 10 concepts.
How much was awarded to NHAI as principal in counter-claims by the tribunal?
The tribunal allowed the counter-claims of the National Highways Authority of India to this extent as principal.
Read the full explanation →What is the length of the Chittorgarh-Udaipur section taken up for six-laning?
This is the length of the Chittorgarh-Udaipur stretch of NH-76 in Rajasthan that was to be widened to six lanes under the concession agreement with Uchit Expressway Private Limited.
Read the full explanation →Under which body was the three-member arbitral tribunal in the Chittorgarh-Udaipur case constituted?
The tribunal that examined the claims and counter-claims flowing from the concession agreement for the Chittorgarh-Udaipur six-laning project was constituted under SAROD and had three members.
Read the full explanation →The arbitration case that NHAI defended in the Chittorgarh-Udaipur stretch concerned which national highway?
The dispute arose from the six-laning of the Chittorgarh-Udaipur section of this highway in Rajasthan, a stretch of 93.5 km.
Read the full explanation →If a free electron moves through a potential difference of 1 kV, then the energy gained by the electron is given by
The energy gained is the charge of the electron multiplied by the potential difference it crosses. Energy W = qV.
Read the full explanation →"The sum of emf's and potential differences around a closed loop equals zero" is a consequence of
The statement is Kirchhoff's voltage (loop) law, and it follows from the fact that energy is neither created nor destroyed.
Read the full explanation →The full form of LED is
An LED is a semiconductor p–n junction diode that gives out light when current flows through it in the forward direction.
Read the full explanation →A car starts from Bengaluru, goes 50 km in a straight line towards south, immediately turns around and returns to Bengaluru. The time taken for this round trip is 2 hours. The magnitude of the average velocity of the car for this round trip
Average velocity is total displacement divided by time, and the car ends where it started, so its displacement is zero.
Read the full explanation →Which one of the following colours may be obtained by combining green and red colours?
When red and green light are added together, the eye sees yellow. Red, green and blue are the primary colours of light.
Read the full explanation →The magnetic field produced by a current-carrying straight wire at a point outside the wire depends
Outside a long straight wire, the field is B = μ₀I/(2πr), so doubling the distance halves the field. This result follows from Ampère's circuital law, or from the Biot–Savart law applied to a long wire.
Read the full explanation →Which one of the following statements about surface tension is correct?
Heating weakens the attraction between the molecules of a liquid, so its surface pulls less tightly. Surface tension arises because molecules at the surface are pulled inward by their neighbours, making the surface behave like a stretched skin.
Read the full explanation →It has been observed that a mirror always forms the image between the pole and the focus, irrespective of the location of the object. Which one of the following is correct in respect of the nature of the mirror?
For any real object, a convex mirror forms a virtual, erect and smaller image behind the mirror, between the pole and the focus.
Read the full explanation →A heating filament and an ideal resistor of fixed value are connected in series with a DC voltage source. After some time, the filament has reached its operating point so that the current in the circuit is steady. Which one of the following is correct?
A metal filament's resistance rises as it heats up, so the current falls and the resistor gets a smaller share of the voltage.
Read the full explanation →Which one of the following is the correct relation between Å and nm?
A nanometre is 10⁻⁹ m and an ångström is 10⁻¹⁰ m, so one nanometre holds ten ångströms.
Read the full explanation →The image we see in plane mirror is
A plane mirror forms an image behind the mirror where light only seems to come from, with left and right swapped.
Read the full explanation →What is the current required to light a 60 W incandescent bulb in a domestic supply of 240 V?
Electric power equals voltage times current, so the current is 60 W ÷ 240 V = 0.25 A. The relation P = VI comes straight from the definitions: voltage is energy per unit charge and current is charge per second, so their product is energy per second, or power.
Read the full explanation →A hollow prism is filled with water of refractive index 1.34 and white light is incident on the prism. The white light is assumed to have wavelengths ranging from 4020 Å to 6700 Å. What is the corresponding wavelength range in water?
When light enters a denser medium, its wavelength is divided by the refractive index of that medium. The frequency of light is fixed by its source and does not change on refraction.
Read the full explanation →The vision of Viksit Bharat @2047, referred to at the session, looks to India becoming a developed nation by which landmark?
The vision of Viksit Bharat @2047, articulated by Prime Minister Narendra Modi, envisages India as a developed nation by the hundredth year of its Independence, and the session on roads was explicitly aligned with it through the goals of supporting economic growth, improving connectivity, strengthening logistics efficiency and widening access…
Read the full explanation →Which two ministries, besides the Ministry of Road Transport and Highways, took active part in the India-Japan Joint Working Group session on roads?
Their presence is logical rather than ceremonial, because a highway alignment, a railway corridor and a power transmission line often compete for the same land and the same clearances, so decisions taken on one affect the others.
Read the full explanation →Which session of the India-Japan Joint Working Group on the roads and road transportation sector was held in New Delhi on 15 October 2026?
The correct answer is the 12th session, held at Bharat Mandapam in New Delhi and organised by the Ministry of Road Transport and Highways.
