Question

In SHM the net force towards mean position is related to its displacement (x) from mean position by the relation

• A. $F\propto x$
• B. $F\propto \frac{1}{x}$
• C. $F\propto x^2$
• D. $F\propto \frac{1}{x^2}$

Answer 1

The correct option is A $F\propto x$

Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.

$F=-kx$

$⟹F\propto x$
