Questions  

The function sin2(ωt) represents

a
A simple harmonic motion with a period 2π/ω
b
A simple harmonic motion with a period π/ω
c
A periodic but not simple harmonic motion with a period  2π/ω
d
A periodic but not simple harmonic, motion with a period  π/ω

detailed solution

Correct option is D

y=sin2ω t=1−cos2ωt2⇒ Period, T=2π2ω=πωThe given function is not satisfying the standard differential equation of S.H.M. d2ydx2=− ω2y. Hence it represents periodic motion but not S.H.M.
