1. A stopper of mass M is tied to a string of length R and swings around horizontally in uniform circular motion with a velocity of v when acted on by a force of F.

What is the period of the stopper?

2. A stopper of mass M is tied to a string of length R and swings around horizontally in uniform circular motion with a velocity of v when acted on by a force of F.

What is the power developed by the force?

3. Two objects, A and B, have equal charge and equal mass. Neither body is in motion because the gravitational and electrostatic forces between them are equal. If the mass of Object A is halved, equilibrium will be maintained if
