364433 A simple second pendulum is mounted in a rocket. Its time period will decrease when the rocket is

1 moving up with uniform velocity
2 moving up with uniform acceleration
3 moving down with uniform acceleration
4 moving around the earth in geostationary orbit
PHXI14:OSCILLATIONS

364435 The time period of a simple pendulum in a stationary van is T. The time period of a mass attached to a spring is also T. The van accelerates at the rate 5ms2. If the new time periods of the pendulum and spring be Tp and Ts respectively, then

1 Tp=Ts
2 Tp>Ts
3 Tp<Ts
4 Cannot be predicted
