Write equation of centripetal acceleration and centripetal force for u

1.	Write equation of centripetal acceleration and centripetal force for uniform circular motion.
Answer» Solution :Whenbody OFMASS m moveson circularpath of radiusr withconstantspeedv ithascentripetalor radialacceleration `a= (v^(2))/( R )`.
