(a) 2E
(b) 4E
(c) E/2
(d) E/4
Show Answer
Answer: (b)
Explanation: Energy ∝ A², so doubling amplitude requires 4 times energy.
Q15. What happens to the period of SHM if amplitude is doubled?
(a) Remains unchanged
(b) Doubles
(c) Halves
(d) Becomes four times
Show Answer
Answer: (a)
Explanation: Time period of SHM is independent of amplitude.
Q16. Which quantity is always zero at the equilibrium position in SHM?
(a) Displacement
(b) Velocity
(c) Acceleration
(d) Kinetic energy
Show Answer
Answer: (c)
Explanation: At equilibrium, acceleration is zero as restoring force is zero.
