Question

If a particle is executing simple harmonic motion, then acceleration of particle :

• A. is uniform
• B. varies linearly with time
• C. is non uniform
• D. Both 2 & 3

Answer 1

The correct option is C is non uniform

Force acting on particle executing SHM,

$F\propto -x$

$x\to$ displacement of particle from mean position

$a\propto -\frac{x}{m}$

a depend on $x$ so, Acceleration of particle is non uniform.
