Problem
A charged spherical shell of radius R carries a total charge Q. Consider a closed cylindrical surface of height h and radius r, with its center coinciding with the center of the shell. The axis of the cylinder is aligned with the center of the shell and is equidistant from the top and bottom surfaces of the cylinder. Let ϕ represent the electric flux through the closed cylindrical surface. The permittivity of free space is denoted by ϵ0. Which of the following statements regarding the flux Φ is/are correct?
