Academics

A 3.0 g aluminum foil ball with a charge of +4.0 x 10^-9C is suspended on a string in a uniform horizontal E? field. The string makes an angle of 30^o with the vertical.

1. If the string is cut, how long will it take the ball to fall to the floor 2.9m below the level of the ball?

2. How far will the ball travel in the horizontal direction while falling?
