Q. Force responsible for the circular motion of the body is
AFMCAFMC 2003Motion in a Plane
Solution:
A body performing circular motion is acted upon by a force which is always directed towards the centre of the circle. The force is called centripetal force. In the absence of this force the circular motion is not possible. If $m$ is the mass of the body and $v$ is velocity and $r$ is radius then magnitude of centripetal force is
$F=\frac{m v^{2}}{r}$
