Question

A particle executes SHM along x-axis with an amplitude A, time period T with origin as the mean position. At t = 0, if the particle starts in the +ve x-direction from the origin the minimum time in which it will be at `x=-A//2` will be
A. `(T)/(12)`
B. `(T)/(6)`
C. `(T)/(4)`
D. `(7T)/(12)`

Answer 1

Correct Answer - D
`-(A)/(2)=Asinomegat,sinomegat=-(1)/(2)impliesomegat=(7pi)/(6)`
`t=(7T)/(12)`.
