BITSAT Physics Question (2023) — Solution

Question

A particle executes SHM of amplitude A. The distance from the mean position when it's kinetic energy becomes equal to its potential energy is

Options

  1. A. 2 ~A
  2. B. 2 ~A
  3. C. 1 2 ~A
  4. D. 1 2 ~A

Answer

C. 1 2 ~A

Step-by-step solution

Let the distance from the mean position is X . Given KE = PE So, 1 2 M ^2 (A^2-x^2 )= 1 2 M ^2 x^2 A^2-x^2=x^2 A^2=2 2 x = A 2
