Answer: 0.0187 times the force between Sun and Earth.
The gravitational force between two massive bodies is directly proportional to their masses and inversely proportional to the square of distance between them.
where G is the gravitational constant.
Let,
The mass of the Sun be
The mass of the Earth be
The mass of the Neptune be
The Distance between Sun and Earth be
The Distance between Sun and Neptune be
It is given that the mass of Neptune is 17 times mass of Earth.
The distance of Neptune from Sun is 30.1 times the distance of Earth from Sun.
The Force between Earth and Sun is
The Force between Neptune and Sun:
