Velocity-time graph of a particle in SHM is as shown in figure. Match the following

Answer

`(A rarr q, B rarr p,q, C rarr r,s)`

Explanation

At P, velocity is zero, but just after few seconds velocity is negative . Therefore , at P particle is at x=+A. At this point acceleration of the particle will be maximum .On similar ground we can say that
At `Q, x=-A`
At R, v is maximum , i.e., paritcle is at mean position, where acceleration is also zero.
