correct me if i am wrong, since the hollow cavity of the conductor is +65, the wall of the hollow part of the conductor is -65, so it stay neutral and the outer surface of the conductor is also +65
if this is true hen way isn't inner wall of the hollow part -130
i multiply by 1/6 because they only want one side of the cube, is that right.
i do not get what you mean by it will no longer be considered a closed surface because they only want one side.
A 10 nC point charge is at the center of a 2.0m x 2.0m x 2.0 m cube. What is the electric flux through the top surface of the cube?
