Homework Help: Electric Potential between two point charges

  1. May 26, 2008 #1
    1. The problem statement, all variables and given/known data

    Two point charges Q1 = +5.00 nC and Q2 = −3.00 nC, are separated by 35.0 cm.
    (a) What is the electric potential at a point midway between the charges?
    (b) How much energy is required to bring an electron, located at infinity, to this midway

    2. Relevant equations

    3. The attempt at a solution
    PE = ke x q1q2/r
