Q20 — Indian Achievements (ISRO, Nuclear Energy) · medium · theory
ISRO uses the GSLV rocket rather than the PSLV for some missions mainly because the GSLV has a:
A. cryogenic upper stage able to reach high geostationary orbits ✓ Correct
B. sail that is pushed by sunlight
C. jet engine that burns air like an aeroplane
D. smaller motor meant only for very low orbits
Solution: The GSLV's powerful cryogenic upper stage lets it place heavy satellites into distant geostationary orbits, which the PSLV cannot reach.
Q21 — Indian Achievements (ISRO, Nuclear Energy) · medium · numerical
India's Mars Orbiter Mission (Mangalyaan) cost about 450 crore rupees, while a comparable foreign Mars mission cost roughly 4500 crore rupees. The Indian mission therefore cost about:
A. one-half of the foreign mission
B. ten times the foreign mission
C. one-tenth of the foreign mission ✓ Correct
D. one-fifth of the foreign mission
Solution: 450 ÷ 4500 = 1/10, so Mangalyaan cost roughly one-tenth as much, making it famous for being very low-cost.

A. 400 MeV
B. 200 MeV
C. 50 MeV
D. 800 MeV ✓ Correct
Solution: Energy is proportional to the number of nuclei split: 4 × 200 MeV = 800 MeV.

A. Thorium ✓ Correct
B. Coal
C. Helium
D. Gold
Solution: India has large thorium reserves in monazite sands, so the long-term nuclear plan is built around thorium as fuel.
Q24 — Indian Achievements (ISRO, Nuclear Energy) · hard · theory
Assertion (A): ISRO launches satellites into polar orbits with the PSLV but uses the GSLV for geostationary orbits. Reason (R): Reaching a geostationary orbit needs a more powerful cryogenic upper stage. Choose the correct option:
A. Both A and R are false
B. Both A and R are true, but R does not explain A
C. A is true but R is false
D. Both A and R are true, and R correctly explains A ✓ Correct
Solution: A geostationary orbit is far higher and demands the extra thrust of a cryogenic stage, which is exactly why the GSLV is chosen over the PSLV.
Q25 — Indian Achievements (ISRO, Nuclear Energy) · hard · numerical
A radioactive fuel sample has a half-life of 8 years. If 80 g is stored today, how much of it will remain after 24 years?
A. 5 g
B. 10 g ✓ Correct
C. 20 g
D. 40 g
Solution: 24 years is 3 half-lives (24 ÷ 8). The amount halves each time: 80 → 40 → 20 → 10 g.
