Help with this problem due tonight!!! Find the direction and magnitude of the net electrostatic for exerted on the point charge q2. There are 4 points of a square. q1 has a charge of -1.6E-6, q2 has a charge of -3.2E-6, q3 has a charge of -4.8E-6, and q4 has a charge of -6.4E-6. The distance between each of the four points around the square is 0.45m. Can anyone show me how to do this, I need to turn it in tonight, I would greatly appreciate it. Thank you.
