    1. The problem statement, all variables and given/known data
    Charge Q is on the y axis a distance a from
    the origin and charge q is on the x axis a
    distance d from the origin.
    What is the value of d for which the x
    component of the force on q is the greatest?

    2. Relevant equations

    3. The attempt at a solution
