Calculating the Kinetic Energy of a Point Charge From Far Away

  1. Feb 13, 2008 #1
    1. The problem statement, all variables and given/known data
    Four point charges form a square with sides of lenght d. Use k as the constant instead of 1/4*pi*epsilon not.

    +q_______-3q



    +2q______+5q

    What would be the kinetic energy for 2q at a very large distance from the other charges? Express answer in terms of q, d, and appropriate constants.


    2. Relevant equations
    U=kqq/r , K=1/2mv^2


    3. The attempt at a solution
    I'm assuming that since the charge is a large distance away, there would be no kinetic energy acting on the charge 2q since it is far away from the forces of the other 3 charges.
