A cylindrical portion of radius r is removed from a solid sphere of radius R and uniform volume charge
density `rho` in such a way that the axis of the hollow cylinder coincides with one of the diameters of the
sphere. (r is negligible compared to R). Then the electric field intensity at point A is"
