Question

Part A
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 = 0.580 kg are dropped from a height of 1.90 m , but one of
the balls is positively charged with q1 = 700 uC , and the
second is negatively charged with q2 = -700 µC .
Use conservation of energy to determine the difference in the speed of the two balls when they hit the ground. (Neglect air resistance.)
Express your answer to three significant figures and include the appropriate units.
