Consider a solid insulating sphere which has a total chargeof +3Q but is distributed as ρ(r) = βr, and has a radius of a. This issurrounded by a conducting shell that has a charge of −3Q placed onits outer surface. The inner radius is b and the outer radius is c. a) Determine β in terms of Q and a.b) Find the potential at all points in space
Two short non-conducting rods of lengths L and 2L are aligned on the y-axis as shown below. The lower rod (-L < y < 0) has a negative linear charge density of -A. The upper rod (0 < y < 2L) has a positive linear charge density of +A. The magnitudes of the linear charge densities are the same such that -A = - (+1) Find the potential V for a point located on the x-axis at x = a due to the presence of both charged rods. Assume V = 0 at infinity. (Hint: Partial symmetry can be used to simplify the problem). +2L (0, 0) -L V-y
