Question

Displacement versus time curve for a particle $SHM$ is as shown in the figure.

Which of the following statements is correct?

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

Answer 1

Answer: (D)

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 $t=6s$.
