Question

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
​

Answer 1

B is correct

Step-by-step explanation:

Maximum Kinetic energy= Work done.

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

Option B is thus correct.
