PhysicsEasysingle choice

The depth from the surface of the earth of radius $R$ , at which acceleration due to gravity will be $60%$ of the value of the value on the earth surface is

Options:

Answer:

Solution:

$g^{'} = g (1 - \frac{d}{R}) g^{'} = 0.6 g ∴ 0.6 = 1 - \frac{d}{R} ∴ \frac{d}{R} = 1 - 0.6 = 0.4 = \frac{2}{5} ∴ d = \frac{2}{5} R$
