Problem: Two stationary positive point charges, charge 1 of magnitude 3.20nC and charge 2 of magnitude 1.95nC, are separated by a distance of 60.0cm. 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 vfinal of the electron when it is 10.0cm from charge 1?
I want help to find the speed vfinal of the electron when it is 10.0cm from charge 1.
