The phase of a particle in `SHM` at time `t` is `(13pi)/(6)`. The following interference is drawn form this

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 displacement of a particle in S.H.M is in opposite phase with

The displacement of a particle making S.H.M. is given by x=6cos(100t+(pi)/(4))m then the frequency is

The variation of velocity of a particle executing SHM with time is shown is fig. The velocity of the particle when a phase change of (pi)/(6) takes place from the instant it is at one of the extreme positions will be
