Two stationary positive point charges, charge 1 of magnitude 4.00nC and charge 2 of magnitude 1.95nC , are separated by a distance of 54.0cm . 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 10.0 from charge 1? Express your answer in meters per second.
