The maximum tension in the string of an oscillating pendulum m is double of the minimum tension. Find the angular amplitude.

cos-1 (3/4)

Given mass = m

Let angular amplitude be

Velocity be V

Tension in the string is maximum at mean position

Tension is minimum at extreme position


= 2

From the law of conservation energy

[loss in P.E is equal to gain in K.E]

Substituting in the above equation
