You are tasked with designing a parallel-plate capacitor using two square metal plates, eachwith an area of 0.5 m², separated by a 0.1 mm thick layer of air. However, to increase the capacitance,you decide to insert a dielectric material with a dielectric constant κ = 3.0 between the plates. Describewhat happens (and why) to the E field between the plates when the dielectric is added in place of theair.
Calculate the work required to assemble a uniform charge Q on a thin spherical shell of radiusR. Start with no charge and add infinitesimal charges dq until the total charge reaches Q, assuming thecharge is always evenly distributed over the shell’s surface. Show all steps.
