A small ball is suspended from a point O by a light thread of length. Then the ball is drawn aside so that the thread deviates through an angle theta from the vertical and set in motion in a horizontal direction at right angles to the vertical plane in which the thread is located. what is the initial velocity that has to be imparted 2g/ to the ball so that it could deviate through the maximum angle(pi)/(2)in the process of motion

A small ball is suspended from a point O by a light thread of length.

1.	A small ball is suspended from a point O by a light thread of length. Then the ball is drawn aside so that the thread deviates through an angle theta from the vertical and set in motion in a horizontal direction at right angles to the vertical plane in which the thread is located. what is the initial velocity that has to be imparted 2g/ to the ball so that it could deviate through the maximum angle(pi)/(2)in the process of motion
Answer» SOLUTION :`SQRT((2GL)/(COSTHETA))`
