Two stationary positive point charges, charge 1 of magnitude 3.75 nC and charge 2 of magnitude 1.55 nC , are separated by a distance of 47.0 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.

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.

Conservation of Energy: In an electrostatic field the mechanical energy of the charged particle is constant. If the charge is moved from an initial point to an end point the gap in potential energy between these two positions is converted into the energy of the charge.
