You don't have any equations you have learned about force and static charges?
 
F=kq1q2/r^2 so do i find the force of each then subtract them? What do i do with each F i find?

i don't know any static charge equations.

What you have given above is the equation that says that two static charges q1 and q2 separated by a distance r, exert a force of F on each other. So why don't you start by determing the Force of the charge at the 0 cm mark on the charge that is in between, the 2uc charge.
