Asolid, dielectric sphere of radius a has a charge of +2q distributed uniformly throughout its volume. a conducting shell with an inner radius of b and an outer radius of c is located concentrically around the solid sphere, and has a net charge of –q.
express all answers in terms of the given values and fundamental constants.
a. use gauss’s law to determine the magnitude and direction of the electric field e at a point located r away from the center of the spheres, where r > c.
b. use gauss’s law to determine the magnitude and direction of the electric field e at a point located r away from the center of the spheres, where b > r > a.
c. plot the electrical field as a function of r from zero to the infinite.
