A small sphere with mass 510^-7 kg and charge is released from rest a distance of 0.500 m above a large horizontal insulating sheet of charge that has uniform surface charge density = 810^-12 C/m^2 .
Using energy methods, calculate the speed of the sphere when it is 0.150 m above the sheet of charge?
