Well, we got our worksheet back today. Everyone who answered D) 7.1 x 10^-6 C got it right. Everyone who answered C) 3.5 x 10^-6 C got it wrong.

Naturally, we asked. He said that in dealing with plate capacitors as a whole, the total charge would have to be zero.

However, when dealing in area, you would need to multiply it by 2 because there are 2 plates.

Then, he said to find the answer to the original post, the equation is q = Eo*A*E, which would be C) 3.5 x 10^-6 C.

Everyone who picked D is now wrong and everyone who picked C is getting extra points.

Its B.S.....I is confused.

So what is the final answer?
