Question

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

[MP PMT 1997; AIIMS 1999; Kerala PMT 2005]

• A. The total energy of the particle always remains the same
• B. The restoring force of always directed towards a fixed point
• C. The restoring force is maximum at the extreme positions
• D. The acceleration of the particle is maximum at the equilibrium position

Answer 1

The correct option is D

The acceleration of the particle is maximum at the equilibrium position

Acceleration $a\propto$ - displacement, and direction of acceleration is always directed towards the equilibrium position.
