Homework Help: Speed of an Electron in an Electric Field

  1. Mar 23, 2010 #1
    1. The problem statement, all variables and given/known data

    Two stationary positive point charges, charge 1 of magnitude 3.90 and charge 2 of magnitude 1.90 , are separated by a distance of 41.0 . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

    2. Relevant equations
    What is the speed of the electron when it is 10.0 from charge 1?

    3. The attempt at a solution
