Explicació
The correct options are:
(A) Restoring force is directly proportional to the displacement. - True (this is a defining characteristic of SHM)
(B) The acceleration and displacement are opposite in direction. - True (the acceleration is proportional to the displacement but in the opposite direction)
(C) The velocity is maximum at mean position. - True (the velocity is zero at the extreme positions and reaches a maximum at the mean position)
(D) The acceleration is minimum at extreme points. - False (the acceleration is maximum at the extreme points and zero at the mean position)
