Energy in SHM

For a particle executing S.H.M., its potential energy is 8 times its kinetic energy at a certain displacement 'xx' from the mean position. If 'AA' is the amplitude of S.H.M., the value of 'xx' is

Show answer and solution

Answer: (c)

  1. PE=8 KE⇒x2=8(A2−x2)PE = 8\,KE \Rightarrow x^2 = 8(A^2 - x^2)
  2. 9x2=8A2⇒x=223A9x^2 = 8A^2 \Rightarrow x = \dfrac{2\sqrt{2}}{3}A
  3. So the answer is (c).
