OK I'm really not understanding any of this, please help, and any tips on how to go about problems like this in general would be much appreciated. 1. The problem statement, all variables and given/known data A point charge Q is situated a distance d from an infinite conducting plate connected to ground. Show that the total charge on the conductor is -Q. 2. Relevant equations I'm not sure but I think the Gauss equations? 3. The attempt at a solution I've found the electric field at any point on the plane to be [kQ/(x^2 + y^2 + d^2)^(3/2)] (-x, -y, d) But like I said, I don't really know what I'm doing!
