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....

Charged sphere in a uniform electric field. Consider the problem of a charged conducting sphere in the uniform external electric field. This is equivalent to the example from the notes with the added charge on the sphere. Find the electric field in the space outside the sphere. Assume that the sphere has radius R and total charge Q. (a) Since there is no charge in the space outside the sphere, this is obviously the case of Laplacian in the azimuthally...
