Two planets have the same average density but their radii are

{R_1}\,and\,{R_2}

. If acceleration due to gravity on these planets be

{g_1}\,and\,{g_2}

respectively, then

View answer and explanation

Correct option: A

\frac{{{g_1}}}{{{g_2}}} = \frac{{{R_1}}}{{{R_2}}}

Option A (

\frac{{{g_1}}}{{{g_2}}} = \frac{{{R_1}}}{{{R_2}}}

) is correct because the acceleration due to gravity is directly proportional to the radius when the average density is the same.
