MHT CET Physics 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 is 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 positionCorrect

Answer: (D)

Solution

Total energy is constant, the restoring force always points to the mean position and is maximum at the extremes, so (a), (b), (c)
