Question about Electric Fields and Charges

[QUOTE="Simon Bridge, post: 5480108, member: 367532"] The question says it is the force [I]on[/I] Q [I]due to [/I]the other three that is zero. You can use your understanding of forces (or electric fields) to work out the directions. i.e. a positive charge to the left of Q contribute an electric field pointing to the right and F=QE The actual value of Q does not matter (you'll see) so you can assume it is positive.
