Find the distance of object placed in the slab of refractive index `mu` from point P of the curved surface of radius R so that image is formed at infinity:

The figure ,shows a transparent sphere of radius R and refractive index mu .An object O is placed at a distance x from the pole of the first surface so that a real image is formed at the pole of the exactly opposite surface. If x=2R ,then the value of mu is
