A slider is oscillating in SHM on an frictionless track with an amplitude A. You slow  it so that its amplitude becomes half. Then the total mechanical energy in terms of  previous value is

a
12
b
13
c
15
d
14

detailed solution

Correct option is D

Initial total energy =12mω2A2 ; final total energy =12mω2A22 .∴ Total mechanical energy becomes 14thExecutives simple harmonic motion is
