Document Summary
Electric charge is distributed uniformly along each side of a square with length a. I: find the electric field in the center of the square if all four sides have positive charge +q. Problem 3: (20 points: a non-uniform, but spherically symmetric, distribution of charge has a charge densityp(r) given as follows: p(r)=p0l for rr p(r)=o forrr. Find the electric field everywhere: a solid conducting sphere with radius r, that carries positive charge q, is concentric with a very thin conducting shell of radius 2r that carries charge -2q. Find the electric field (magnitude and direction) in each of the regions 0 2r. Draw schematically the electric field 1: for part b) find a difference in electric potential between points r = 0 and r = Two horizontal conducting rails form an angle 8 where their ends are joined.
