metal-coated table tennis ball with a mass of 2.1 g is suspended by an insulating thread. A similar table tennis ball touches the first, giving each ball an equal negative charge. When the two balls are separated horizontally by 5.0 cm, the string hangs at 15 with respect to the vertical. Determine approximately how many excess electrons are on each table tennis ball.
