Step-by-step explanation:
A small bead of mass m can moves on a smooth circular wire (radiusR) under the action of a force F=(km)/r^(2) directed (r=position of bead from P&K=constant) towards a point P with in the circle at a distance R/2 from the centre what should be the minimum velocity of bead at the point of the wire nearest the centre of force (P) so that bead
