Question

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

Answer 1

 The formula for the magnitude of gravitational force between the earth and an object on its surface is

$$

F=G \frac{M_{e} m}{R_{e}^{2}}

$$

where $F$ is the gravitational force.

$G$ is the gravitational constant.

$M_{e}$ is the mass of the earth.

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

$R$ is the radius of the earth
