Force of Friction
The force of gravity on the hooked masses supplies the tension in the string which in turn supplies the centripetal force that keeps the body rotating.It would be better to say that the weight of the hanging masses IS the centripetal force that keeps the body revolving.... and so the two forces are equal because there is really on one force.
No; "centripetal" implies an inward force.
no, but rotation can produce centripetal force
Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force

friction
The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
No; "centripetal" implies an inward force.
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.

Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force
The gravitational force IS the centripetal force in this case.
centripetal- Dashun Walden
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
Centripetal acceleration is proportional to the square of the speed (a = v2/r). Therefore, according to Newton's Second Law, centripetal force is also proportional to the square of the speed.
