A second pendulum is attached to roof of a car that is sliding down along a smooth inclined plane of inclination `60^(@)`. Its perios of oscillation is

A

2s

B

`sqrt(2)`s

C

`2 sqrt(2)` s

D

1s

Text Solution

Verified by Experts

The correct Answer is:
C
`(T^(1))/(T) = sqrt((g)/(g_(eff))) = sqrt((g)/(g cos theta))`
`(T^(1))/(2) = sqrt((1)/(cos 60^(@)))`
`rArr T^(1) = 2 sqrt(2) s`
