Question

A particle executes a simple harmonic motion of time period T. Find the time taken by the particle to go directly from its mean position to half the amplitude.
A. T/2
B. T/4
C. T/8
D. T12

Answer 1

Correct Answer - D
`y=asin omegat=(a sin 2pi)/(T)t`
At the mean position `y=a/2`
`a/2=(asin 2pit)/(T)`
`t=T/12`
