Question

In a body executing SHM, acceleration is maximum at
(a) Both ends
(b) Mean position
(c) Both (a) and (b)
(d) None of these​

Answer 1

Answer:

a

Explanation:

see the acceleration at both ends is -w^2y this acceleration produces a force called restoring force which tries to bring it to mean position that will be w^2A

  from above we can infer accleration is directly proportional to the displacement so this displacement is max at amplitude as amplitude is the gratest displacement from mean position

where w is angular velocity

           y is displacement

           A is amplitude
