A transparent sphere of radius `R` and refractie index `mu` is kept in air. At what distance from the surface of the sphere shold a point object be placed so as to form a rea image at the same distance from the sphere?

A transparent sphere of radius R and refractive index n is kept in air. At what distance from the surface of the sphere should a point object be placed on the principal axis so as to from a real image at the same distance from the second surface of the sphere.
