Question

The acceleration (a) of SHM at mean position is :

• A. zero
• B. $\propto x$
• C. $\propto x^2$
• D. None of these

Answer 1

The correct option is A zero

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.

$F=-kx=ma$

$⟹a=\frac{-kx}{m}\propto x$

At mean position ,$x=0$

$⟹a_{mean}=0$
