Considering Earth to be a sphere of radius $R$ having uniform density $\rho$,the value of acceleration due to gravity $g$ in terms of $R$,$\rho$,and $G$ is:

  • A
    $g=\sqrt{\frac{3 \pi R}{\rho G}}$
  • B
    $g=\sqrt{\frac{4}{3} \pi \rho GR}$
  • C
    $g=\frac{4}{3} \pi \rho GR$
  • D
    $g=\frac{GM}{\rho R^2}$

The value of the acceleration due to gravity is $g_{1}$ at a height $h = \frac{R}{2}$ ($R$ = radius of the earth) from the surface of the earth. It is again equal to $g_{1}$ at a depth $d$ below the surface of the earth. The ratio $\left(\frac{d}{R}\right)$ equals
