There is a body having mass m and performing S.H.M. with amplitude a. There is a restoring force F = –kx. The total energy of body depends upon
-
- k, x
- k, a
- k, a, x
- k, a, v
Correct Option: B
| Total Energy of body performing simple harmonic motion = | mω2 a2 = | ka2 | ||
| 2 | 2 |
where k = mω2
 | T.E. = K.E. + P.E. = | m(a2 - x2) ω2 + | mω2 x2 |  | ||
| 2 | 2 |
Hence energy depends upon amplitude and k (spring constant).
