Question 2 Page 134 - Chapter 10 Class 9 - Gravitation (Term 2)

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.

Answer

Let the mass of earth = M

Let the mass of the object = m

Distance between the the earth’s centre and object = Radius of the earth = R

Therefore,

Gravitational Force = F = GMm/ R ²
