Question

A and b are two objects.What happens to the force between two objects if.I.The mass of a is doubled.Ii. The distance between a and b are doubled.Iii.The masses of both a and b are doubled

Answer 1

firstly the gravitational forces act between them.

1.. if mass is dobled then forces between them will be increased.

2. if the distance will double then the forces between them will be less 4 time

3.. if the mass of both object is double then forces will be dobled

the reason of happening this is

$f \: is \: drecty \: \:proportinal \: to \: mas \\ \\ and \: inversaly \: proportional \: to \: distane$
