Let me help you telling you this: you need to use the electric force equation which is:Fe=kcq1q2/r2

Three times to first calculate the three individual electric forces acting on q3. kc is Coulomb's constant = 8.99 x 10^9 N*m^2/C^2 Once you have found the forces q1q3, q2q3, and q4q3 you need to add the vectors to find the net force.

I think it will help you get through
