Question

For Simple Harmonic Oscillator, the potential energy is equal to kinetic energy

• A. twice during each cycle
• B. four times during each cycle
• C. when $x=0$
• D. when $x=a$

Answer 1

Answer: (B)

Total energy = $P \, E \, + \, K \, E$ .
When a particle executes SHM, there is one position between maximum amplitude and mean position where $PE$ is equal to $KE$ , and particle have to cross that point four times to complete one oscillation.
