Question
Acceleration 
and time period 
of a body in S.H.M. is given by a curve shown below. Then corresponding graph, between identic energy (K.E) and time 
is correctly represented by
The correct answer is:
In S.H.M. when acceleration is negative maximum or positive maximum, the velocity is zero so kinetic energy is also zero. Similarly for zero acceleration, velocity is maximum so kinetic energy is also maximum
