Question: A metal ball with a mass of 3.09x10-6 kg and a charge of +4.13 mC has a kinetic energy of 4.97x108 J. It is traveling directly at an infinite plane of charge with a charge distribution of +3.51 C/m2.
Part A: If it is currently 1.75 m away from the plane of charge, how close will it come to the plane before stopping?
I need help to find how close it will come to the plane before stopping.
