The mass and diameter of a planet have twice the value of the corresponding parameters of earth. Acceleration due to gravity on the surface of the planet is

Options:

Answer:

Solution:

$\frac{g^{'}}{g} = \frac{M^{'}}{M} {(\frac{R}{R^{'}})}^{2}$

$\frac{g^{'}}{g} = (\frac{2 M}{M}) {(\frac{R}{2 R})}^{2} = \frac{1}{2}$

$\Rightarrow$ $g^{'} = \frac{g}{2} = \frac{9.8}{2} = 4.9 m s^{- 2}$
