A non-uniform charge distribution, in a medium with relative dielectric constant & = 3, causes an Electric field given by the following expression. = x3yz +96xyz +29xyz2 V/m V/m. for y > 0. This Electric field is next to an infinite conducting surface, which is placed at y = 0. Determine the following (a) The volume charge density function (pv) that caused this electric field in region y >0 (b) The surface charge density (ps) on the conducting surface (y=0) (c) The potential difference between the points P (2,0,1) and Q (1,1,1) (7) - (9)
