A student says that he had applied a force F = – 
on a particle and the particle moved in simple harmonic motion. He refuses to tell whether k is a constant or not. Assume that he has worked only with positive x and no other force acted on the particle .
Text Solution
Verified by ExpertsThe correct answer is:
A
Given F = – K 
——
For SHM F = –K 1 x ——
From eqn. and K = K 1 
∴ F = – K 1 
= –K 1 x.
Here K = K 1 
⇒ K ∝ 
As x increases K increases.
