Q. A simple pendulum hanging from the ceiling of a stationary lift has time period $t_{1}$. When the lift moves downward with constant velocity, the time period is $t_{2}$, then
A) $t_{2}$ is infinity
B) $t_{2} > t_{1}$
C) $t_{2} < t_{1}$
D) $t_{2} = t_{1}$
Explanation
(d) The lift is moving with constant velocity so, there will be no change in the acceleration hence time period will remain same.
