Question

mass of the earth is doubled and raduis is half. how the gravity will be affected


​

Answer 1

Answer:

F'= F/2

Explanation:

The original gravity = F

F = GMm / r^2

New force = F'

F'= G 2M m / (2r)^2

F'= 2 GMm / 4 r^2

F'= F /2

So the gravity will be affected as it will reduce by half.
