the period of oscillation of a simple pendulum of length `L` suspended from the roof of a vehicle which moves without friction down an inclined plane of inclination `prop`, is given by.

A

`2pisqrt((L)/(gcosalpha))`

B

`2pisqrt((L)/(gsinalpha))`

C

`2pisqrt((L)/(g))`

D

`2pisqrt((L)/(g tanalpha)`

Text Solution

Verified by Experts

The correct Answer is:
A
Effective gravity=`g cos alpha` therefore `T=2pisqrt((L)/(g cos alpha))`
