A point charge q1 = 15.00 microC is held fixed in space. From a horizontal distance of 8.0cm, a small sphere with mass 4.00*10^-3 kg and charge q2 = +2.00 microC is fired toward the fixed charge with an initial speed of 41.0 m/s. Gravity can be neglected.
A) What is the acceleration of the sphere at the instant when its speed is 29.0 m/s
