A square plate of copper with 54.0 cm sides has no net charge and is placed in a region of uniform electric field of 84.0 kN/C directed perpendicularly to the plate.(a) Find the charge density of each face of the plate.(b) Find the total charge on each face.
The electric field for a charged sheet is given by: E ρ /εo free space permitivity: ε 8.85x10^-12 C?/N m? ρ εoE 8.85x10^-12(84x10?) 7.43x10^-7 C/m? Q ρA 7.43x10^-7(0.54?) 2.16x10^-7 C 21.6 uC
