## Homework Statement

What is the Net force (include direction) acting on charge Q2 due to Q1 and q? (ans: Fnet = 174N right)

## Homework Equations

F=kQ

_{1}Q

_{2}/r

^{2}

E=F/Q

## The Attempt at a Solution

I've figured out a) and b). It's just c) that's giving me trouble. I tried using the first equation - (9.0 x 10

^{9})(4.1 x 10

^{-4})(3.0 x 10

^{-6})/2

^{2}but this isn't anywhere near the answer.

I've tried using F=EQ → (2.0 x 10

^{6})(4.1 x 10

^{-4}) = 820N. Still very far off.
