Answer #1

The gravitational force acting on two massive bodies is given by the equation:

F = G M m / r^2

where F is the force of gravity, G is the gravitational constant, M is the mass of one body, m is the mass of the other body, and r is the distance between their centers of mass.

F = 1.6 x 10^23 N

and F is inversely proportional to r^2

if earth is 4 times as far as of now then the resulting gravitational force between them is F' = F/16

F = 0.1 x 10^23 N
