1. Image charges in sphere We have two charges of magnitude +Q seperated by a distance of 2d, see drawing. a) Find a grounded conducting sphere (potential set to zero) with radius R, where R is the m...
1. A hollow conducting sphere of radius R has a charge Q placed on its surface. A point charge Q1 is placed at a distance d> R from the center of the sphere. a) Using the method of superposition, find a combination of two image charges inside the sphere that result in the correct electric field and potential outside the sphere. b) What is the force between the sphere and the point charge? What is the force whern 0, and...

2. Gauss' Law See Figure 1. A solid, conducting sphere of radius a has total charge (-)2Q uniformly distributed along its surface, where Q is positive. Concentric with this sphere is a charged, conducting spherical shell whose inner and outer radii are b and c, respectively. The total charge on the conducting shell is (-)8Q. Find the electric potential for r < a. Take the potential out at infinity to be 0.
Points: 1 13) Is it possible to have a zero electric potential between two positive charges along the line joining the two charges? A) Yes, if the two charges are equal in magnitude. B) No, a zero electric potential cannot exist between the two charges. C) Yes, regardless of the magnitude of the two charges. D) cannot be determined without knowing the separation between the two charges E) cannot be determined without knowing the magnitude of the charges Points: 3...
