I need help with the following question. A diopole is made up of two charges, Q1 and Q2, that are seperated by a distance of 1 meter. Q1 has a charge of +3C and Q2 has a charge of -3C. What is the electric field strength of the field set up by these two charges at a point exactly halfway between them? I know the formula for this type of question, and it seems fairly simple as far as just entering in the values, but I'm having a hard time figuring out what Q and the distance is going to be.
