Q. The centripetal acceleration of a particle of mass $m$ moving with a velocity $v$ in a circular orbit of radius $r$ is
A) $v^{2}/\ r$ along the radius, towards the center
B) $v^{2}/\ r$ along the radius, away from the center
C) $mv^{2}/r\ $ along the redius, away from the center
D) ${mv}^{2}/\ r$ along the radius, towards the center
Explanation
