Q.
A simple pendulum has time period T1. The point of suspension is now moved upward according to the relation y = kt2, (k =1ms2) where y is the vertical displacement. The time period now becomes T2. The ratio of T21T22 is (Take g = 10 ms2)

Q.
A simple pendulum is suspended from the ceiling of a car accelerating uniformly on a horizontal road. If the acceleration is a0 and the length of the pendulum is l, find the time period of small oscillations about the mean position.
g+a
Particle won't oscillate with fixed time period
Q.
A simple pendulum hanging from the ceiling of a stationary lift has a time period T1. When the lift moves downward with constant velocity, the time period is T2, then
T2 is infinity
T2> T1
T2< T1
T2 = T1
