What happens to the energy of a simple harmonic oscillator if its amplitude is doubled?

a
E2 = 2E1
b
E2 = 4E1
c
E2 = 8E1
d
E2 = E1

detailed solution

Correct option is B

, Energy =E=12mω2A2 ⇒Energy α  amplitude2                    A=amplitude ⇒E1E2=A1A22 here in question A2 = 2A1                            ⇒E2=4E1
