Physics pain.

Okay so before I get to the bit that the title is about I just want you to know a few things.

My ranking for the webcomics I've read in the past decade based on Art, Story, and general

That was the answer to my problem the other day. The one about the charged ring. Following you'll see my
current bane and hate filled nemesis.

A cube has one corner at the origin and the opposite corner at the point (L,L,L). The sides of the cube are parallel to the coordinate planes. The electric field in and around the cube is given by \vec{E} = (a+b x)\hat{x} + c\hat{y}.
Find the total electric flux Phi_E through the surface of the cube.
Express your answer in terms of a, b, c, and L.

hahahahahahaha [the crying starts here]

I always struggled with the electrical parts of physics, and it seemed like most of my class in first year did as well.

Everyone was horrified when then professor told us the final would only be on material from the second half of the year, so we wouldn't have as much to study. Of course the second half of the year was all electrical.
