Problem: A point charge q1=15.00uC is held fixed in space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00*10^-3kg and charge q2=+2.00uC is fired toward the fixed charge with an initial speed of 37.0m/s. Gravity can be neglected.
Part A: What is the acceleration of the sphere at the instant when its speed is 26.0m/s?
I need help to determine the acceleration of the sphere at the instant.
