There are 4 equal charges of 2 micro Coulumbs in a shape of a square. 2 positives line up on 1 side, which is the left side and 2 negatives line up on the other side, which is the left. Again, the charges are of equal magnitude.
The question asks for the magnitude of the electric field at the center...
I was thinking it's zero, but I'm not quite sure if that's true.
The other question is if you put a -4 micro Coulumb charge at the center, what will be the magnitude force on it and direction?
I know the 2 positive charges are attracted to the negative charge, therefore there are two vector arrows coming out of the postive charges into the -4 micro C charge, but I don't which direction the arrow goes when it comes to the 2 negatives. Is there a arrow that comes out of the -4 charge towards the negative charage, or an arrow from the negative charge to the -4 charge. Since it's repulsive i don't know which one.
Any help is appreciated...thx
