Defence GK Questions 2026

Trishakti Manthan was the event organised as part of the Silver Jubilee, featuring addresses by the Chief of Defence Staff and by the Chief of Integrated Defence Staff, and it is not described as a standing institutional mechanism of the kind listed in the other options.

Under this theme HQ IDS organised Trishakti Manthan, released a Silver Jubilee Book and a film on its milestones, and conferred CDS Unit Citations on personnel.

HQ IDS was established in New Delhi on that date, and the day is observed every year as Tri-Service Day; the organisation therefore completed 25 years and celebrated its Silver Jubilee under the theme of future readiness through jointness and integration.

The correct answer is Mombasa, the Kenyan port where the frontline stealth frigate berthed for a goodwill call during her deployment.

The visit of the Indian warship to the Kenyan port has been placed within the spirit of this framework, which expresses India's approach to working with friendly countries of the Indian Ocean Region on both security and development.

That is how the ship has been described in the announcement of her visit to the Kenyan port, and a frigate of this class is a general purpose warship built with a reduced radar signature so that it is harder to detect at sea.

The Commanding Officer, officers and crew of the ship laid a wreath at the Mazargues War Memorial in Marseille in remembrance of 205 Indian soldiers who made the supreme sacrifice during the World Wars.

The Ministry of Defence stated that INS Trishul arrived at Toulon to join the twenty-fourth edition of the exercise, which makes Varuna one of the longest-running bilateral naval exercises India takes part in.

Varuna is the annual bilateral maritime exercise between the Indian Navy and the French Navy, and in its twenty-fourth edition the Indian warship Trishul sailed to the French port of Toulon to take part.

In a prokaryotic cell the genetic material lies free in the cytoplasm with no nuclear membrane around it, and this poorly defined nuclear region is called the nucleoid.

A medium that holds less water than the cell is a hypertonic medium, so water moves out of the cell by osmosis and the cell shrinks.

Hydrogen is a colourless, odourless and tasteless gas, so none of the colours listed fits it.

Graphite is soft and slippery rather than hard, so this is the statement that is not correct. The difference between the allotropes comes from the way the carbon atoms are joined.

An emulsion is a colloid in which one liquid is spread as fine droplets through another liquid that does not mix with it.

Ethyl acetate is an ester, and esters are the family of organic compounds known for a sweet, fruity smell. It is formed when ethanol reacts with acetic acid in the presence of a little concentrated sulphuric acid, a reaction called esterification, and its formula is CH3COOC2H5.

Three grams of hydrogen, 48 grams of oxygen and 42 grams of nitrogen each come to 1.5 moles, while two grams of carbon is only about 0.17 mole, so carbon holds a different number of particles.

A colloid only looks uniform to the eye; it is in fact a heterogeneous mixture, so this is the statement that is not true.

Copper sulphate holds five water molecules, sodium carbonate ten and gypsum two, so the order asked for is 5, 10 and 2.

The statement in the question is Avogadro's law, given by the Italian scientist Amedeo Avogadro in 1811.

A simple pendulum about one metre long completes one full swing in roughly two seconds, and a pendulum of this length is called the seconds pendulum.
