Question: Let V = 10( + 1)z 2 cos V in free space. (a) Let the equipotential surface V = 20 V define a conductor

Let V = 10(ρ + 1)z2 cos ϕ V in free space.

(a) Let the equipotential surface V = 20 V define a conductor surface. Find the equation of the conductor surface.

(b) Find ρ and E at that point on the conductor surface where ϕ = 0.2π and z = 1.5.

(c) Find |ρS| at that point.
