Centripetal force does no work' - explain.

For uniform circular motion, does the direction of the centripetal force depend on the sense of rotation (i.e., clock-wise or anti- clock wise)?

Statement I: In a circular motion, work done by centripetal force is not always zero. Statement II: If speed of the particle increases or decreases in circular motion, net force, acting on the particle is not direction towards the centre.

The centripetal force necessary for an artificial satellite revolving along its orbit around the earth is delivered by

Dimensionally prove the expression (mv^(2))/( r) for the centripetal force F acting on a particle of mass m moving with velocity v in a circle of radius r.
