A particle performing S.H.M. with the initial phase angle is /2. Then the particle is at

MHT CET Physics question

A particle performing S.H.M. with the initial phase angle is . Then the particle is at

Answer: (A)

With x = A sin( t + /2) = A cos( t), at t = 0 the displacement is A, so the particle is at the extreme position where displacement is
