The potential energy, U of three simple harmonic oscillators varies with displacement x as shown in the figure. These oscillators have the same mass but different amplitudes A1 , A2 and A3 . Their characteristic frequencies ν1 , ν2 and ν3 are related to each other as:
(a) V1/A1 = V2/A2 = V3/A3
(b) ν1Α1 = v2Α2 = v3Α3
(c) ν1 > ν2 > ν3
(d) ν1 <ν2 < ν3
