A simple pendulum of length l and mass (...

A simple pendulum of length l and mass (bob) m is suspended vertically. The string makes an angle `theta` with the vertical. The restoring force acting on the pendulum is

A

`mv^(2)//L`

B

`mg.cos theta + mv^(2)//L`

C

`mg.cos theta -mv^(2)//L`

D

`mg.cos theta`

Text Solution

Verified by Experts

The correct Answer is:
B

From the figure `T = mg cos theta + mv^(2)//L`
