Homework Statement
Two point charges are placed on the x axis: +5 microC charge at x=0 and +8 microC charge at x=0.9m. Where on the x-axis can a third charge be placed so that the net charge on all three charges is zero? Determine the magnitude of the third charge.
Homework Equations
E=[tex]\frac{kQq}{r2}[/tex]
The Attempt at a Solution
It's difficult to type on here but basically I let E of the two given charges equal each other to find a point but I have no idea how to complete the rest of the question. The given answer is a charge of -1.56[tex]\mu[/tex]C at x=0.397m.
Thank you
