A100 g ball on a 60-cm-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?

Explanation:

Given

mass of ball

Length of string

ball reaches to a height of

let us take initial velocity of ball at the time of breaking be u and v be the final velocity at top

using

If T is the Tension in the string, then T is given by

as technology advances, new experiments often expose problems in accepted theories. c
