Answer:
A and C
Explanation:
Kinetic energy of a body is given by the expression,
, where v is the velocity and m is the mass of body.
In case of a simple pendulum the maximum velocity is at it's stationary position.
So maximum velocity i at position C, which means maximum kinetic energy is at position A.
The velocity of pendulum reduces as the angle between vertical stationary and current position increases.
So, velocity at E and A are the minimum, so at A and E the kinetic energy value is minimum.
Now examining the options given, we will understand the kinetic energy increase is maximum in case of A and C.
