Homework Statement
you have a +3C and a -1C charge on the x axis. the +3C charge is at the origin and the -1C is at x=1. At what point on the positive x-axis does E=0?
Homework Equations
E=kQ/r^2
The Attempt at a Solution
So i have
E=(-1k/r^2)+(3k/(1+r)^2)
Setting E=0
1k/r^2=3k/(1+r)^2
r= sqrt(0.5) = 0.707
is this correct?
