Problem: Two stationary positive point charges, charge 1 of magnitude 3.30nC and charge 2 of magnitude 2.00nC, are separated by a distance of 50.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.
Part A: What is the speed v final of the electron when it is 10.0cm from charge 1?
