Q. The graph shows the variation of displacement of a particle executing S.H.M. with time. We infer from this graph that
A) The force is zero at time $3T/4$
B) The velocity is maximum at time $T/2$
C) The acceleration is maximum at time $T$
D) The P.E. is equal to total energy at time $T/2$
Explanation
(d) At time $\frac{T}{2};v = 0\ \therefore$ Total energy = Potential energy
