2.
A charge Q is located at the origin. A cube of
side a has one corner at the origin and exists
in the region where x, y, z are positive.
a. Find the electric flux through side 1.
b. Find the electric flux through side 2. For this
solution, you should get the following integral
whose solution is,
$\int_0^a \frac{dx}{(x^2 + a^2)\sqrt{x^2 + 2a^2}} = \frac{\pi}{6a}$
