Redistribution of charges for concentric spherical shells where one shell is grounded

Two concentric spheres of radius R and 2R have charges Q and 2Q. The potential at a point P situated at a point 3R/2 distance from common centre is V, Now if outer sphere is earthed, the potential at point P is:
Before earthing,the potential at P,
so,
After earthing the outer sphere, potential at P,
