1 How does force of attraction between two objects change when the distance between them - Science - Force and Laws of Motion

Question

1 How does force of attraction between two objects change when
the distance between them is reduced to half?
2 What happens to the force between the two objects, if
(i) The mass of one object is doubled?
(ii) The distance between the objects is doubled
3 Calculate the force of gravitation between the earth and the
sun, given that the mass of the earth = 6x1024 kg and of the sun =
2x1030 kg The average distance between the two is 1 5 x 1011 m

Dear Student
Gravitational force of
attraction=Gm1m2r2 where m1 and m2 are the masses and r is the distance between masses1 Force of attraction becomes four times when r becomes half2 (i) when mass of one object is doubled than the force becomes double
(ii) when distance becomes double than the force of attraction becomes 14 times
