A particle of mass $M$ moves with constant speed along a circular path of radius $ r$ under the action of a force $F$. Its speed is
$\sqrt {\frac{{r\,F}}{m}} $
$\sqrt {\frac{F}{r}} $
$\sqrt {F\,m\,r} $
$\sqrt {\frac{F}{{m\,r}}} $
A particle of mass $M$ moves with constant speed along a circular path of radius $ r$ under the action of a force $F$. Its speed is
$F = \frac{{m{v^2}}}{r}$
$⇒$ $v = \sqrt {\frac{{rF}}{m}} $
