Your image is not able to be viewed. Could you please specify where the charges are located?

If not, this problem just involves using Coulomb's Law multiple times. Simple use the equation to find the force acting on the -6.1 uC point charge from each of the other charges. The net force is simply the vector sum of all the individual forces.

Coulomb's Law:$$F = k\frac{q_{1}q_{2}}{r^{2}}$$
