A mine is located at depth $\frac{R}{3}$ below earth's surface. The acceleration due to gravity at that depth in mine is ( $R =$ radius of earth, $g$ = acceleration due to gravity)

Options:

Answer:

Solution:

The acceleration due to gravity at depth $d$ is $g_{d} = g (1 - \frac{d}{R})$ given $d = R /3$ $∴ g_{d} = g (1 - \frac{( R /3 )}{R}) = \frac{2}{3} g$
