Question

The earth remains in orbit around the sun due to the force of gravity. How does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

Answer 1

The sun is bigger than the earth, therefore it has more gravitational force than the earth.

Answer 2

Answer:

The force remains same.

Explanation:

Let the mass of sun is M and the mass of earth is m. The distance between them is d.

According to the Newton's law of gravitation, the force between the two bodies is directly proportional to the product of their masses and inversely proportional to the square of distance between them.

Thus, the force exerted by the sun on earth is equal to the force exerted by the earth on sun are same which is given by

$F = G\frac{M\times m}{d^{2}}$
