Near the surface of the Earth there is an electric field of about 150 V/m which points downward. Two identical balls with mass m = 0.540 kg are dropped from a height of 2.00m, but one of the balls is positively charged with q1 = 650μC, and the second is negatively charged with q2 = – 650μC. Use conservation of energy to determine difference in the speed of the two balls when they hit the ground. (Neglect air resistance)
