Simple Harmonic Motion

A particle starts oscillating simple harmonically from its mean position with time period '\(T\)'. At time \(t=\frac{T}{12}\), the ratio of the potential energy to kinetic energy of the particle is \(\left(\sin 30^{\circ}=\cos 60^{\circ}=0.5, \cos 30^{\circ}=\sin 60^{\circ}=\sqrt{3} / 2\right)\)
