10 pts. (3) A small charged ball of m = 10.0 g is suspended by a non-conducting string in a uniform electric field E as shown in Figure 2. The magnitude of uniform electric field Ě is: E = 4000 N/C a- What is the sign of the charge on the ball ? b- If the ball is in equilibrium when the string makes an angle a = 12.0° with the ver- tical as indicated in Figure 2. What is the net charge on the ball ? Figure 2:
