Two large rectangular aluminum plates of area 140 cm face each other with a separation of 3 mm between them. The plates are charged with equal amount of opposite charges, 125 UC. The charges on the plates face each other. Find the flux (in N . m /C) through a circle of radius 3.5 cm between the plates when the normal to the circle makes an angle of 90 with a line perpendicular to the plates. Note that this angle can also be given as 180 + 90. X N . m / c
