Two large flat parallel sheets have opposite uniform surface charge densities to and are separated a distance d. A large, uncharged conducting slab of thickness d/3 is parallel to the charged sheets, centered between them. First, using Gauss' law, prove that charge must be induced on the surfaces of the slab, and find the surface density of this charge. Then find the electrostatic potential as a function of distance y perpendicular to the sheets. Take the reference potential Vo = = 0 and the origin y = 0 to be at the negative sheet. -

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
