Question

the force f acting on a body depends on mass m ,moving in a circle of radius r with a velocity v with help dimensions drive relation bat them.

Answer 1

$f \: = mv {}^{2} \div r \:$
Hope it helped you....

Answer 2

when any body move in circular motion ... force change into torque .... then this is equal to centripetal force

F=mvsqure/ r
