Please help?!?

In figure 20-1, where is the field of each charge the strongest?
The picture shows A. A postive charge with arrows facing out and B. A negative charge with the arrows pointing in.

This is a short answer question, but I don't understand what kind of answer they want.
Can someone help or give me a link to where I can learn about this?

electric field by definition is the direction a positive charge would go. A is correct. B is correct. Now which is strongest? depends on the size of the charges, and the distance from the charge.

E=kq/r^2
