Aslab of charge with charge density p(z) = 2 poz/d extends from z = -d/2 to z= +d/2 and is infinite in extent in the x - and y directions. assume the permittivity in all regions is 80. (a) using the principle of superposition and results proved in lectures, write down an expression for the electric field e(z) everywhere within and outside the slab of charge. provide all working. (b) verify that your answer satisfies gauss' law in differential form. (c) write down an expression for the electric potential $(z) at points inside and outside the slab. (d) calculate the total energy per unit area stored in the slab using your answer to (a).

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.
