Two stationary positive point charges, charge 1 of magnitude 4.00 nC and charge 2 of magnitude 1.80 nC , are separated by a distance of 44.0 cm. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.
A: What is the speed V(final) of the electron when it is 10.0 cm from charge 1? Express your answer in meters per second.
