Question

If the Mass of
Earth in doubled and the radius is halfed what will be
the value of acceleration due to gravity​

Answer 1

Answer:

it would be 8.1

hope it helps

Answer 2

Given the law of universal attraction, as it depends on the mass, and the inverse of the square of the distance, if the mass of the earth was doubled, and its radius was halved, earth's gravity constant would be multiplied by 8, which means that it would become equal to 9.81*8=78.48.

Hope it will help you :)
