Q1. For three coplanar vectors A, B and C, (A × B)·C = ?
- Null vector
- 3
- 0
- ABC
Show the answer
Answer: C. 0
A × B is perpendicular to the plane, so its dot product with the in-plane vector C is zero.
Q2. At what launching angle does the horizontal range of a projectile become equal to its maximum height?
- 45°
- 76°
- 60°
- 30°
Show the answer
Answer: B. 76°
R = H gives tan θ = 4, so θ ≈ 76°.
Q3. A 500 kg rocket travels in deep space at a constant speed of 3000 m s⁻¹. The power being produced by the rocket engine at this time is:
- 1500 kW
- 6 kW
- 0.16 kW
- None of these (zero)
Show the answer
Answer: D. None of these (zero)
At constant velocity in deep space there is no net force, so no power is needed.
Q4. The ratio of angular frequency to linear frequency is:
- 1/2π
- 4π
- All of these
- 2π
Show the answer
Answer: D. 2π
ω = 2πf, so ω/f = 2π.
Q5. Sound waves show which property?
- Reflection
- Refraction
- Interference
- All of these
Show the answer
Answer: D. All of these
Sound can be reflected, refracted and can interfere.
Q6. Addition of heat at constant pressure to a gas results in:
- Raising its temperature and doing external work
- Raising its pressure
- Raising its temperature only
- Raising its volume only
Show the answer
Answer: A. Raising its temperature and doing external work
At constant pressure the gas both heats up and expands, doing work.
