Q.
Acceleration $A$ and time period $T$ of a body in S.H.M. is given by a curve shown below. Then corresponding graph, between identic energy (K.E) and time $t$ is correctly represented by
A)
B)
C)
D)
Explanation
(a) 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
