Question

If Earth had twice the mass it has now, how would the gravitational force between it and the Sun change?

The gravitational force would be the same as it is now.

The gravitational force would be four times as much as it is now.

The gravitational force would be half as much as it is now.

The gravitational force would be twice as much as it is now.

Answer 1

The gravitational force would be twice as much as it is now

Step-by-step explanation:

If the earth had twice its mass as it is now, the gravitational force between the sun and the earth would be twice as much as it is now.

According to Newton's law of universal gravitation "the gravitational force of attraction between bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them". Therefore, the force will double.
