For this physics II problem its saids a 4.00 g ping pong ball is suspended from a light thread and given an electric charge. The ball is then placed in a uniform electrci field of magnitude 110,00N/C which causes the ball to swing out to an angle of 23 degrees. What is the sign and magnitude of the charge on the ball? The ball is angled to the right. If you can break this down into step that would be great. Thanks!
