A body of mass 40 kg is tied at one end of a string of length l. The body is oscillating in a vertical plane with angular amplitude` theta_0` . What is the tension in the string when it makes and angle `theta` with the vertical ? If the breaking load for the string is 80 kgf, what can be the maximum angular amplitude of the body ?

Text Solution

Verified by Experts

The correct Answer is:
`392 (3 cos theta -2cos theta_0)N , 60^@`
