Charge Q is uniformly distributed inside a sphere of radius R. (a) Determine the electric field inside and outside the sphere. Explain how you arrive at the answer. (b) A cavity of radius R/4, and centered at a point a distance R/2 from the center of the sphere, is made within the sphere. This means that within the sphere of radius R, there is a smaller sphere of radius R/4 which has no charge (the charge density is zero within...

Problem 2: a conducting sphere A conducting sphere has a positive net charge Q and radius R. (Note: since the sphere is conducting all the charge is distributed on its surface.) a) By reflecting on the symmetry of the charge distribution of the system, determine what the E-field lines look like outside the sphere for any r > R. Describe the E-field in words and with a simple sketch. Make sure to also show the direction of the E-field lines....
