Two stationary positive point charges, charge 1 of magnitude 3.95nC and charge 2 of magnitude 1.60nC , are separated by a distance of 44.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the speed Vf (final velocity) of the electron when it is 10.0cm from charge 1? Express your answer in meters per second.
