Which one of the circle will act greater force on the object when the object is embedded between two rotating concentric circle?PHYSICS-"circular motion". Your answer is necessary to me! I think circle of smaller radius will act greater force on the object in radially outward direction that is centrifugal force. Since two opposite force is acting on the object. One is centrifugal force=mv^2/r and other is centripetal force=mv^2/R.Clearly,(centrifugal force)mv^2/r> mv^2/R(centripetal force) [ R>r]Hence, the force on object due to smaller circle is greater. Is it right or wrong? Please correct me with explanation!
