The variation of acceleration due to gravity $g$ with distance $d$ from the centre of the earth is best represented by ( $R$ = Earth's radius):

Options:

Answer:

Solution:

We know that acceleration due to gravity is given by,

$|g| = \{\begin{matrix} \frac{G M r}{R^{3}}, & 0 \leq r < R \\ \frac{G M}{r^{2}}, r \geq R \end{matrix}$

$∴$ The desired graph is,
