For what value of displacement the kinetic energy and potential energy of a simple harmonic oscillation become equal?
Options
- Ax = 0
- Bx = ± A
- Cx = ± A 2
- Dx = A 2
Correct answer
C. x = ± A 2
Step-by-step solution
K E = P E 1 2 m ω 2 A 2 - x 2 = 1 2 m ω 2 x 2 A 2 - x 2 = x 2 2 x 2 = A 2 x = ± A 2
