What is the magnitude of the electric field at a point midway between a -5.9 uC and a +8.2 uC charge 8.8 cm apart? Assume no other charges are nearby. Express your answer using two significant figures: E= (what value) in (what units)? What is the direction of the electric field? Toward the positive charge Toward the negative charge P.S. I know nothing about this but I have a good idea are some quick google help. I feel like I understand the concept but I want to verify the work before I'm able to help a friend with this problem. It would be helpful if you can list all the steps- I can reverse engineer with no issues.
