For example, let's say there was an block infinitely long in the x and y direction and in the z direction bounded by positive and negative a.
I am trying to find the charge of a imaginary partition infinitely long in the x and y direction and in the z direction bounded by positive and negative b, where b is less than a.
Here is where I get confused, if the charge density is something like p = p0*(a^2 - z^2), where z in the case is b, as mentioned above.
dQ = p * dV
Do i integrate from here or do I substitute in p = p0*(a^2 - z^2), and then integrate?
