Considering earth to be a sphere of radius '$$R$$' having uniform density '$$\rho$$', then value of acceleration due to gravity '$$g$$' in terms of $$R, \rho$$ and $$\mathrm{G}$$ is

$$g=\sqrt{\frac{3 \pi R}{\rho G}}$$

$$\mathrm{g}=\sqrt{\frac{4}{3} \pi \rho \mathrm{GR}}$$

$$\mathrm{g}=\frac{4}{3} \pi \rho \mathrm{GR}$$
