Question

Example 1: The gravitational force of attraction between Earth and the sun is 1.6*10^23 N.
What would this force have been if Earth were twice as massive?​

Answer 1

As one mass increases, the gravitational force between the two bodies increases proportionally. Therefore, if Earth's mass were doubled, the gravitational force between the sun and Earth would double as well. Example 2: The gravitational force of attraction between Earth and the sun is 1.6 1023 N.
