A point charge q 1 = +5.00 C is held fixed in space. From a horizontal distance

A point charge q₁ = +5.00 µC 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 µC 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?
