Two material particles of equal masses are performing simple harmonic oscillations whose graphs are

shown. If E1 and E2 are their energies of oscillation, then

A

E1> E2

B

E2> E1

C

E1 = E2

D

Information is insufficient to decide.

Answer

E1 = E2

Explanation

Solution

Using E = 12\frac{1}{2}2 A2; frequency of oscillation of wave 2 is double but amplitude is half hence E1 = E2.
