Find the tension in the string an instant before it broke

Reference no: EM13315201

A 300g ball on a 70cm -long string is swung in a vertical circle about a point 200 cm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height 600 cm above the floor.

What was the tension in the string an instant before it broke?
