Which force does balance centripetal force?

For example if we are rotating a ball tied with a string then centripetal force is acting inwards. Then which force balances it. I thought it is the centrifugal force but it is a pseudo force.

There is no force that balances the centripetal force, and because of this, you get acceleration inward and circular motion. If the force were balanced, you would get no acceleration, and no circular motion.

Well i guess that at the point which the rope is held or tied ; to keep that thing stationery the rope exerts force on the hand(screw/ axle) OPPOSITE to the force that is exerted on rock(bob) by it.

hand -T----->-----------------------------<------O (bob)
