Time period of a simple pendulum is 2s. ...

Time period of a simple pendulum is 2s. If its length is increased by 4 times, then its period becomes……….

A

`16s`

B

`12s`

C

`8s`

D

`4s`

Text Solution

Verified by Experts

The correct Answer is:
D
`T propto sqrt(l)`
`(T_1)/(T_2)= sqrt((l_1)/(l_2))`
`(2)/(T_2)= sqrt((l)/(4l)) implies T_(2)= 4s`.
