1.

A simple harmonic oscillation has an amplitude `A` and time period `T`. The time required to travel from `x = A` to ` x= (A)/(2)` isA. `(T)/(6)`B. `(T)/(4)`C. `(T)/(3)`D. `(T)/(12)`

Answer» Correct Answer - A
In equation `x = Acos omega t`, putting `x = (A)/(2)` we get
`omega t = (pi)/(3)`
`:. ((2pi)/(T))t = (pi)/(3)`
or `t = (T)/(6)`
