Question

A particle of mass m is rotating in a circular path of radius r its angular momentum is j the centripetal force acting on the particle would be

Answer 1

The Centripetal force expression is given by:

                        $F = M*v^{2}/ r$

• Where M is the mass of the body, r is the radius of circular path and v be the velocity of motion.

• The angular moment j is given by:

                        $j = M*v*r\\\\v = j/(M*r)$

• Hence substituting v in the force expression we get:

 

                   $F = j^{2}/(M*r^{3} )$
