Question

Centrifugal force ?????

Answer 1

A force acting on a body away from the centre of the circular path is known as centrifugal force.

Answer 2

${\boxed{\tt{Centrifugal\:Force\:!!}}}$

★Rotation of a body in a circular path and the centripetal force vanishes, the body would leave the circular path.

★To an observer A, who is not Sharing the motion along the circular path, the body appears to fly off tangentially at the point of release.

★To another observer B, by which motion is sharing by circular path (i.e., the observer B is also rotating with the body which is released, it appears to B, and if it's thrown off along the radius from the centre with some force. The inertial force is called Centrifugal Force.)

★It's Magnitude is equal to that of the centripetal force = mv²/r.

★Centrifugal Force is a fictitious force which has to be applied as a concept only in a rotating frame of reference to apply N.L in that frame.
