Homework Statement
Two charges, -26 µC and +5 µC, are fixed in place and separated by 1.3 m.
(a) At what spot along a line through the charges is the net electric field zero? Locate this spot relative to the positive charge. (Hint: The spot does not necessarily lie between the two charges.)
Homework Equations
E = k*q/r^2
The Attempt at a Solution
26e-6k / d^2 = 5e-6k / (1.3 - d)^2
i solved for that and got d = .9037 and d = 2.32 ...since i need them pointing in the same direction its the one that is not between them. i understand that...and it all seems right.
Does anyone get something different?
It is an odd #'d problem so i looked at the question in the book and was able to work it to get the right answers for the book version, but my online #s are different and while i work it very similarly and it all makes logical sense. I get them wrong :(
Any tips?
