Homework Statement
Two point charges of -2.5 µC and 6.0 µC lying along the x-axis are 1.0 m apart. Locate the point (other than infinity) at which the total electric field is zero.
Homework Equations
I was thinking: E=F/q
and
F=K (Q x q)/d^2
But I'm not quite sure how to use them.
The Attempt at a Solution
Using the second equation I found F to be -.135. But I don't think that's right, and then when plugging that into the E=F/q. E would have to be zero, since I'm trying to find where the total electric field is zero? Then there's no solutions other than infinity, are there? And what exactly is q in the first equation. I really have no idea what's going on here.
