A point charge q1 = +5.00 mC is held fixed in space. From
Chapter 23, Problem 23.46(choose chapter or problem)
A point charge q1 = +5.00 mC is held fixed in space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00 * 10-3 kg and charge q2 = +2.00 mC is fired toward the fixed charge with an initial speed of 40.0 m>s. Gravity can be neglected. What is the acceleration of the sphere at the instant when its speed is 25.0 m>s?
