A Particle Executes Simple Harmonic Oscillations With An Amplitude A Physics Question

A particle executes simple harmonic oscillations with an amplitude a. The period of oscillation is T. The minimum time taken by the particle to travel half of the amplitude from the equilibrium position is

Options

(a) T/8
(b) T/12
(c) T/2
(d) T/4

Correct Answer:

T/12

Explanation:

Displacement from the mean position y = a sin(2π / T) t
According to the problem y = a/2
a/2 = a sin (2π / T) t
⇒ π / 6 = (2π / T) t ⇒ t = T / 12
This is the minimum time taken by the particle to travel half of the amplitude from the equilibrium position.
