Question

The situation below shows a cross section through an infinite system that consists of a non-conducting slab (with a non-uniform charge distribution) and a conducting slab. On the non-conducting slab, there is a charge per volume of ? = +5x3, where x is measured in meters and x=0 is taken to be the left edge of the slab. Initially, the conducting slab has a positive layer of charge of +2 C/m2 on its left face and no other excess charges. Later, at equilibrium, the charge on the conducting slab has been redistributed. (a) Find the magnitude and direction of the electric field at point A, the midpoint of the non-conducting slab. (b) Find the magnitude and direction of the electric field at point B, the midpoint between the slabs. (c) Find the magnitude and direction of the electric field at point C, the midpoint of the conducting slab. (d) At equilibrium, find the charge per area (specify the magnitude and sign) that settles on the left face of the conducting slab.
