linear superposition

[Brewer]

this principle does apply to electric fields doesn't it?

If I have two (different) charges in different positions, and the question asks for the electric field (mag and direction) at another point, I can find them separately and then add them together (using vectors of course) can't I?

Yes.

Yes, you can find the electric field strength using the summation of vectors.

Thanks guys.

So with any luck my answer is correct then!
