Task id12408
A ball of mass m=2.0 g, having a charge q=2.5•10-9 C, is suspended on a thread and moves along a circle of radius R=3 cm so that the thread rotates with an angular velocity w=2 rad/s. A ball with the same charge was placed in the center of the circle. What should the angular speed of rotation of the thread become so that the radius of the circle along which the ball moves does not change?
