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

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 $t = 1\,s$ and $t = 5\, s$. Also phase is same when $t = 2\, s$ and $t = 6\, s$.
