A linear harmonic oscillator of force constant 2×10^6 N/m and amplitude 0.01m has a total mechanical energy of 160J. Its ___________
(a) Potential energy is 160 J
(b) Potential energy is zero
(c) Potential energy is 100J
(d) Potential energy is 120J
I got this question in an interview for job.
My doubt stems from Oscillations topic in chapter Oscillations of Engineering Physics I
