[#996] A system exhibiting S.H.M. must possess
Correct Answer

(A) Elasticity as well as inertia

Explanation

Solution: Basic conditions to execute simple harmonic motion are: (i) There must be an elastic restoring force acting on the system, (ii) the system must have inertia, and (iii) the acceleration of the system should be directly proportional to its displacement and is always directed to mean position.

[#997] Which of the following is an example of simple harmonic motion?
Correct Answer

(B) Simple pendulum motion

Explanation

Solution: When a body moves about a mean position in such a way that the acceleration is proportional to the displacement and is always directed towards the mean position, the body is said to execute a simple harmonic motion. The motion of a simple pendulum falls under this category.
