Electromagnetics HW.4 Group. 3 Deadline 2/8/89 1) A spherical distribution of charge exist in the region . This charge distribution is concentrically surrounded by a conducting shell with inner radius and outer radius . Determine and V everywhere. 2) Three charges are arranged along the z-axis at , respectively. a)Determine V and E at a distant point b)Find the equations for equipotential surfaces and streamlines. 3) Consider a sphere with radius and electrical potential . We put this sphere in a new dielectric media with constant . Find the potential of sphere in the second condition. 4) A dielectric sphere of radius is centered at the origin. A uniform electric field(without the dielectric sphere) is applied . The potential( with the sphere) is given by a) Find for b) Find for c) Find
