SI unit of gravitational constant G.

The astronomical object closest to us is

The force between a hollow sphere of mass $M$and a point mass $‘m’$at P inside it (Shown in figure): ($PC=X$, Radius $=r$) 

Value of $G$ on surface of earth is $6. 673 \times {10}^{-11} \mathrm{N} {\mathrm{m}}^2/{\mathrm{kg}}^2$, then value of $G$ on surface of Jupiter will be
