Question

Write the formula to find the magnitude of the gravitational force between the earth and a body on the surface of the earth.

Answer 1

Definition of Gravitational force

Gravitational force is defined as a force of attraction with which all the physical bodies attract each other. It is a non-contact type of force.

The formula for the gravitational force between the earth and a body on the surface of the earth.

The magnitude of the gravitational force between the earth and a body on the surface of the earth is given as,

Gravitational Force,

$F=\frac{GMm}{r^2}$

Where,

$G$ is the universal gravitational constant.

$M$ is the mass of the earth.

$m$ is the mass of the body on the surface of the earth.

$r$ is the distance between the earth and that body.
