A small ping-pong ball of mass m = 0.025 kg and charge q = 140 μC is suspended vertically by a string of length L = 0.5 m in an electric field of strength E = 2500 N/C. In Case A, the electric field is directed vertically downward. In Case B, the electric field is directed horizontally to the right causing the ping-pong ball to make an angle θ with the vertical. In Case A, what is the tension T in the string suspending the ping-pong ball?
