Displacement versus time curve for a particle executing SHM is shown in figure. Choose the correct statements.

Options

A. Phase of the oscillator is same at t=0 s and t=2 s.
B. Phase of the oscillator is same at t=2 s and t=5s
C. Phase of the oscillator is same at t=1s and t=7 s
D. Phase of the oscillator is same at t=1s and t=5s.

Answer

D

Explanation

The phase of a particle executing SHM is defined as the state of a particle as regards to its position and direction of motion at any instant of time. In the given curve, phase is same when t=1s and t=5s. Also phase is same when t=2s and t=6s.
