A small plastic ball of mass m = 1.50 g is suspended by a string of length L = 15.5 cm in a uniform electric field, as shown in the figure below. If the ball is in equilibrium when the string makes a e = 14.0" angle with the vertical as indicated, what is the net charge on the ball? Fr E-1.00 x 10 N/C
