This is a Multiple Choice Questions as classified in NCERT Exemplar

Answer-a, c, d

Explanation- acceleration due to gravity at altitude g’= $\frac{g}{{(1 + \frac{h}{R})}^{2}} \approx g (1 - \frac{2 h}{R})$

At depth d, g’=g (1-d/R)

In both cases value of g decreases

But in case of latitude the value of g increases when we increase $\emptyset$

$g_{\emptyset} = g - w^{2} R {c o s}^{2} \emptyset$

also we conclude from the formula that it is independent upon mass.

$\frac{G M m}{{(R + x)}^{2}} = \frac{G M m (R - x)}{R^{3}}$

->R³ = (R + x)² (R – x)

->R³ = (R²– x²) (R + x)

->x² + Rx – R² = 0

$x = \frac{- R \pm \sqrt[]{R + 4 R^{2}}}{2}$

$x = \frac{(\sqrt[]{5 R} - 1)}{2} R$
