A linear harmonic oscillator of force constant 2 × 106

Home » Physics of Sound » Oscillations » Question

A linear harmonic oscillator of force constant 2 × 10⁶ N/m and amplitude 0.01 m has a total mechanical energy of 160 J. Its

1. potential energy is 160 J
2. potential energy is 100 J
3. potential energy is zero
4. potential energy is 120 J

Correct Option: B

Force constant k = 2 × 10⁶ N/m
Amplitude (x) = 0.01 m

Potential Energy =	1	kx²
	2

=	1	× (2 × 10⁶) × (0.01)² = 100 J
