A particle of mass m is performing linear simple harmonic motion. Its equilibrium is at $x = 0$ , force constant is K and amplitude of SHM is A. The maximum power supplied by the restoring force to the particle during SHM will be at what displacement?

Options:

Answer:

Solution:

Power from the restoring force: $P = F v = K x ω A^{2} - x^{2}$ .

Setting $\frac{d P}{d x} = 0$ gives $A^{2} - 2 x^{2} = 0$ , so $x = \frac{A}{2}$ .
