A ball of mass 10^(-2) kg and having charge + 3 xx 10^(-6)C is tied at one end of a 1m along thread. The other end of the thread is fixed and a charge - 3 xx 10^(-6) C is placed at this end. The ball can move in the circulr orbit of radius 1m in the vertical plane. Initially, the ball is at the bottom. Find the minimum initial horizontal velocity of the ball, so that it will be able to complete the full circle.
