If the masses of the earth and the sun were each multiplied by 3 without changing the distance between them, the gravitational force between the two bodies would be the present gravitational force between them.

Force will will become 9 times the previous value

Explanation:

Let the mass of earth is , mass of sun is and distance between them is R

From law of gravitation force between sun and earth is given by

, here G is gravitational constant

From the relation we can see that gravitational force is proportional to mass of them

And in question it is given that mass of both is multiplied by 3

So new force will be equal to

So force will will become 9 times the previous value

9 times

Explanation:

Let the mass of sun is Ms and the mass of earth is Me. The distance between them is R .

The gravitational force between the two is given by

As both the masses is multiplied by 3, and the distance between them remains same, then the force becomes 9 times.

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
