A particle moves in a straight line with retardation proportional to its displacement. Its loss of kinetic energy for any displacement $\mathrm{X}$ is proportional to
Text Solution
Verified by ExpertsThe correct answer is:
A
This condition is applicable for simple harmonic motion. As particle moves from mean position to extreme position its potential energy increases according to expression $U = \frac{1}{2} k x^{2}$ and accordingly kinetic energy decreases.
