The displacement of a particle in simple harmonic motion in one time period is [A = amplitude]

A) A

B) 2 A  

C) 4 A

D) Zero

Correct Answer: D

Solution :

[d] As seen from figure after one time period the bob return to its equilibrium position, so diplacement of the particle is zero, but distance covered by the particle in one time period is 4A (where A is amplitude of bob, when it does S.H.M.)
