Chapter 24, Problem 48EAP

FIGURE P24.48 shows two very large slabs of metal that are

parallel and distance $l$ apart. The top and bottom of each slab

has surface area A. The thickness of each slab is so small in

comparison to its lateral dimensions that the surface area around

the sides is negligible. Metal I has total charge Q₁ = Q and metal 2

has total charge Q₂ = 2Q. Assume Q is positive. In terms of Q

and A, determine

a. The electric field strengths E_l to E₅ in regions 1 to 5.

b. The surface charge densities ${\eta }_a$ to ${\eta }_d$ on the four surfaces a

to d.
