Electric field due to a point charges

[joerylee palmerola]

Suppose a charge q is placed at point x=0, y=0. A second charge q is placed at point x=8.0m, y=0. What charge must be placed at the point x=4.0m, y=0 in order that the field at the point x=4.0m, y=3.0m be zero?

You need to show at least some thoughts or ideas about the solution, even if you can't proceed very far with it.
