1. The problem statement, all variables and given/known data A point charge q is situated a distance d/2 above a square surface of side d as shown (see attached). a) It cannot be determined b) 2q/ε0d c) q/4[itex]\pi[/itex]ε0 d) q/[itex]\pi[/itex]ε0d2 e) q/6ε0 2. Relevant equations [itex]\Phi[/itex]=qenc/ε0=[itex]\oint[/itex]E*dA 3. The attempt at a solution Shouldn't the answer be zero because whatever enters the area also leave the area? If not I know I should use the integral of E*dA but I don't know what E would be.
