Two stationary positive point charges, charge 1 of magnitude 3.25nC and charge 2 of magnitude 1.60nC , 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. What is the speed v_final of the electron when it is 10.0cm from charge 1? Express your answer in meters per second.
