For a particle executing simple harmonic motion , which of the following statements is NOT correct?

Options

  1. AThe magnitude of acceleration is directly proportional to displacement.
  2. BThe restoring force is always directed towards fixed point.
  3. CThe restoring force is maximum at extreme position.
  4. DThe acceleration of the particle is maximum at equilibrium position.

Correct answer

D. The acceleration of the particle is maximum at equilibrium position.

Step-by-step solution

In simple harmonic motion, the acceleration of a particle is given by a = - ^2 x , where x is the displacement from the equilibrium position. At the equilibrium position, the displacement x = 0 . Substituting x = 0 in the expression for acceleration, we get a = 0 . Thus, the acceleration of the particle is minimum (zero) at the equilibrium position, not maximum. The restoring force F = -kx is directed towards the equilibrium position and its magnitude is maximum at the extreme positions where x = A . Therefore, the
