A seconds pendulum is mounted in a rocket. Its period of oscillation decreases when the rocket:

A

moves round the Earth in geo-stationary orbit

B

moves up with uniform acceleration

C

comes down with uniform acceleration

D

moves up with a unifrom velocity

Text Solution

Verified by Experts

The correct Answer is:
B
`T=2pisqrt((l)/(g)).` When the rocket accelerates upwards g increases to (g + a).
