A positive charge of 2.6 µC is pulled on by two negative charges. One, -2.0 µC, is 0.050 m to the north and the other, -4.0 µC, is 0.025 m to the south. What total force is exerted on the positive charge?

i've tried adding the three chages after plugging in charges 1+3 2+1 and 1+3 into Kq1q2/r^2 i can not solve it

how do you figure this out how do you find the force when you have three chages acting on one another
