Q3 Consider a uniformly charged infinite line lying along the z axis in a 3D space.Assume uniform charge density p and use Figure 3 as a guide. Evaluate the scalar potential in a(ro, 0o, 0). Consider L < opoint with coordinate (r, 0, z) Hence or otherwise, derive the expression for the electric field E at a generic point on the plane z = 0, and evaluate such expression in the limit for L → infinity
