from positive to negative.
 
So if you have two charges, where would they be in B?

ummm... no, it can't be B.
 
You could try drawing two point charges and sketch some electric field lines.
None of the pictures is perfect, but see which one looks a bit like your sketch (or rather, two sketches, because ...)

Yes, thank you~
 
Are you sure the problem is asking about Electric fields? I get a different answer if they are talking about magnetic fields... :smile:
