The phase of a particle in S.H.M. is `pi//2`, then :

The phase of a particle executing S.H.M is pi//2 when it has

The acceleration of a particle in S.H.M. is

The acceleration of a particle in S.H.M. is

The displacement of a particle in S.H.M. is given by x= B "sin" (omega t + alpha) . The initial position (at time t=0), of the particle is the initial phase angle if the angular frequency of the particle is pi rad//s ?

The phase of a particle performing S.H.M. when the particle is at a distance of amplitude from mean position is

The phase of a particle performing S.H.M. increases by pi//2 after every 4 seconds. Its time period of oscillation is
