Let `theta` denote the angular displacement of a simple pendulum oscillating in a vertical plane. If the mass of the bob is m, the tension in the string is `mg cos theta`

Text Solution

Verified by Experts

The correct Answer is:
A, C
At the extreem position, velocity of the pendulum is zeor,
So there is no centrifungal force
`:. T=mg cos theta
