Question

write the formula to find the magnitude of the gravitational force between the earth an object on the surface of the earth .​

Answer 1

Explanation:

Let m1 be the mass of the Earth and m2 the mass of an object on its surface. If r is the radius of the Earth, then according to the universal law of gravitation, the gravitational force (F) acting between the Earth and the object is given by the relation:

F=(Gm_1 m_2)/r^2

Answer 2

Explanation:

• The gravitational force between the earth and an object on the surface of the earth is

Mm

F = G d²

• Where G is the universal gravitational constant

• M is the mass of earth

• m is the mass of object on the surface of earth

• d is the distance between the two bodies.
