A point charge q = -2.80 μC has a fixed position. A tiny ball of mass 8.00 g is charged Q = -6.20 μC and shot toward the point charge. When the ball is 75 cm from the point charge, its speed is 17.0 m/s. What is the speed of the ball when it is 35 cm from the point charge? Treat the ball as a point charge and ignore weight.
