प्रश्न
Displacement vs. time curve for a particle executing S.H.M. is shown in figure. Choose the correct statements.
- Phase of the oscillator is same at t = 0 s and t = 2s.
- Phase of the oscillator is same at t = 2 s and t = 6s.
- Phase of the oscillator is same at t = 1 s and t = 7s.
- Phase of the oscillator is same at t = 1 s and t = 5s.

उत्तर
b and d
Explanation:
It is clear from the curve that points corresponding to t = 2s and t = 6s are separated by a distance belonging to one time period. Hence, these points must be in the same phase.
Similarly. points belonging to t = 1s and t = 5s are at a separation of one time period, hence must be in phase.
