## Homework Statement

A point charge with charge q1 is held stationary at the origin. A second point charge with charge q2 moves from the point (x1,0) to the point (x2,y2).

How much work is done by the electrostatic force on the moving point charge?

Express your answer in joules. Use k for Coulomb's constant (k = 1/4*pi*epsilon.

## Homework Equations

W = Uf-Ui = delta U

k q1*q2/[(1/r2 - 1/r1]

## The Attempt at a Solution

I don't know how to attempt when there are no q values and no r values. Please help.
