Question

Obtain an expression for the centripetal force required to make a body of mass m
moving with a speed V around a circular path of radius.r​

Answer 1

Explanation:

the correct expression for the body moving in circular path with constant velocity has a force acting on it with magnitude F=mv²/r

Answer 2

Answer:

rate of change of tangential velocity is called as the centripetal acceleration.

F=
