Three point charges lie in a straight line along the y-axis. A charge of q1 = -9.50 µC is at y = 6.30 m, and a charge of q2 = -7.20 µC is at y = -4.00 m. The net electric force on the third point charge is zero. Where is this charge located?
y = m
y = m

set up the two force equations:
kq1q/(6.40-x)^2= kq2q/(4+x)^2
solve for x
kq1q/(6.40-x)^2= kq2q/(4+x)^2
solve for x
