When a particle undergoes simple harmonic motion, its acceleration is proportional to

Options

Athe distance it has travelled since t = 0
Bits displacement from the mean position
Cits speed
Dits distance from the mean position

Correct answer

B. its displacement from the mean position

Step-by-step solution

For a particle executing simple harmonic motion, the restoring force acting on it is directly proportional to its displacement from the mean position and is directed towards the mean position. F = -kx ma = -kx a = - k m x = - ^2 x Thus, the acceleration of the particle is directly proportional to its displacement from the mean position.
