Hi welcome to OPenstudy!
First thing you have to do is to draw a diagram:
|dw:1403195176755:dw|

Find R by using pythagorean theorem which is $c^2=a^2+b^2$

After you solve for the distance R, calculate the $F_E$ on each charge by using the formula: $\Large F_E=\frac{kq_1q_2}{r^2}$.

But the problem is you don't know if these charges are positive or negative.
