Which of the following conditions is not...

Which of the following conditions is not sufficient for SHM and why?
(i) acceleration`prop` displacement,
(ii) restoring force `prop` displacement.

Text Solution

Verified by Experts

Condition (i) is not sufficient, because direction of acceleration is not mentioned. In SHM, the acceleration is always in a direction opposite to that of the displacement.
