3) the maximum angular displacement of a pendulum in simple harmonie motion is theta, max then the kinetic energy is equal to the potential energy when the angular displacement is given by

B is correct

Explanation:

Maximum Kinetic energy= Work done.

Now, Work done=mgh=mg(L−Lcosθ)=mgL(1−cosθ)

Option B is thus correct.

scorpions are,
