A simple pendulum of length l is suspended from the ceiling of a cart which is sliding without friction on an inclined plane of inclination θ. What will be the time period of the pendulum?

Question

A simple pendulum of length

l

is suspended from the ceiling of a cart which is sliding without friction on an inclined plane of inclination

θ

. What will be the time period of the pendulum?

2 π \sqrt{\frac{l}{g \cos θ}}

2 π \sqrt{\frac{3 l}{g \cos θ}}

4 π \sqrt{\frac{2 l}{g \cos θ}}

3 π \sqrt{\frac{4 l}{2 g \cos θ}}
