Question

The value of acceleration due to gravity on a planet ‘A’ is ‘g’ What will be the value of acceleration due to gravity on another planet B whose mass is same as that of the planet ‘A’ but its radius is double the radius of planet ‘A’ ?

Answer 1

Explanation:

use formula

$g = gravitational \: const \: \times mass \: of \: planet \div square \: of \: its \: radius$

then ans will come

g(b)=g(a)/4
