Question

Starting from the centre of the earth having radius R, the variation of g (acceleration due to gravity) is shown by :

Easy

A
B
C
D

Solution

$\begin{aligned} g = (\frac{{GM}_{e}}{R_{e}^{3}}) r for 0 < r \leq R_{e} \Rightarrow g \propto r \\ g = \frac{{GM}_{e}}{r^{2}} for r \geq R_{e} \Rightarrow g \propto \frac{1}{r^{2}} \end{aligned}$
