Question

what is the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth
​

Answer 1

Answer:

Newton's Law of Gravitation

Directly proportional to the product of their masses i.e. F ∝ (M1M2) . . . . (1) Inversely proportional to the square of the distance between their centre i.e. (F ∝ 1/r2) . . .

Explanation:

Answer 2

Weight is defined as the gravitational force between the object and the earth surface.

• It is also defined as the product of acceleration due to gravity and mass of the object  i.e.   F = m × 9.8 m/s^2
• The magnitude of the object in earth surface and  gravitational force is given by; F = GMm/d^2
