Two large rectangular aluminum plates of area A face each other with a separation of d between them. The plates are charged with equal and opposite charge of magnitude q. The charges on the plates face each other. Find the flux through a circle of radius r between the plates when the normal to the circle makes an angle of θ degrees with a line perpendicular to the plates. Note that the circle's area is less than that of the...
