Thanks for your solution, I understand it now! I have one question regarding symmetry. I apologize as I'm still studying Gauss' Law so I hope to not come across as clueless. I thought the symmetry argument only applied to spherical, cylindrical, and planar surfaces. In the case of a large cube...

The correct answer is B, but I am not sure why. I have a few confusions regarding this problem. First of all, I had thought that we cannot use Gauss' Law to determine the flux through a SIDE of a cube since Gauss' Law only works for SURFACES. How can we determine how an electric field pierces a...

Ah, I see. How do we get an indication of the direction of the field if we are not given the sign of charge Q?

The answer according to the key is C. I thought the answer would be E since the electric field inside a conductor is always zero. Can someone explain why the answer is C?
