Finding the Electric Field Between Charges [picture]

[PeachBanana]

Homework Statement

5. There are two charges in space. In which region of the line connecting these two
charges can we find a point of zero electric field?

Homework Equations

None.

The Attempt at a Solution

I know this isn't even that hard. I was thinking it was somewhere in the middle because the charges are attractive but this is not so.

The charges aren't attractive, they both are positive. They are repulsive

Yikes I drew that picture incorrectly! That should read negative 5C. I'm redoing it now.
