[SOLVED] Griffiths problem 2.37 1. The problem statement, all variables and given/known data Two large metal plates (each of area A) are held a distance d apart. Suppose we put a charge Q on each plate; what is the electrostatic pressure on the plates? 2. Relevant equations 3. The attempt at a solution I am so helplessly lost with this problem. How do I get the electric field just outside of the surfaces of the plates? Its not a capacitor since the charges are not opposite!
