A point charge q is located at the center of a sphere of radius R.The sphere is then surrounded concentrically by a uniform ring having linear charge density $\lambda$ and radius a (a >R).The flux through the sphere is

Gauss's law states that the electric flux through a closed surface is equal to the charge enclosed by that surface divided by the permittivity of free space. Since only the point charge q is enclosed by the sphere, the flux through the sphere depends solely on q, regardless of any external charges.
