Hey yall. This is a question from my homework but it's so basic that it's just to help with the concept for me. So the question is this: A small object A, electrically charged, creates an electric field. At a point P located 0.250 directly north of A, the field has a value of 40.0 directed to the south. What is the charge of object A? I know there is a formula, is it perhaps E=F/q) E= 2kq/d ? And if it is, what is plugged in for what? Help please!
