Write equation of centripetal acceleration and centripetal force for uniform circular motion.

Explanation

When body of mass m moves on circular path of radius r with constant speed v it has centripetal or radial acceleration `a= (v^(2))/( R )`. Direction of acceleration is toward centre of the circle which is shown in figure

by newtons second law of motion necessary force to provide this acceleration `f_(c ) = (mv^(2))/( R )`
In different situation centripetal force is provided as follows
(1) For planet revolving around the sun necessary centripetal is provided by gravitational force.
(2) For electron revolving around uncleus in atom necessary centripetal force is provided by coulombain force
(3) for vehicles moving on level cirular track necessary centripetal force is provided by friction force between tye and road.
