Neptune has a mass that is about 17 times the mass of earth. the distance between the sun and neptune is about 30.1 times the distance between the sun and earth. if the gravitational force between the sun and earth is 3.5 x 1028 n, which is closest to the force between neptune and the sun?

Explanation:

As we know that gravitational force of sun on earth is given as

now we will have

= mass of sun

= mass of earth

so here force is given as

now we know that

mass of Neptune is 17 times mass of earth

distance of Neptune from sun is 30.1 times the distance of Earth from sun

so here the force between them is given as

now we will have

now plug in the value of force F

a person with a mass of 106kg has a weight of 1060n
