The mass of a planet and its diameter are three times those of earth’s. Then the acceleration due to gravity on the surface of the planet is: $(g = 9.8 m s^{- 2})$

Options:

Answer:

Solution:

$g_{p l a n e t} = \frac{G (3 M_{e})}{{(3 R_{e})}^{2}}$
$g = \frac{G M_{e}}{{R_{e}}^{2}}$
$g_{p l a n e t} = \frac{9.8}{3} \approx 3.3$ $m s^{- 2}$
