Question

calculate the force between two objects that have masses of 20 kg and 100 kg separated by a distance of 2.6 m

Answer 1

The gravitational force between the objects is $1.97\cdot 10^{-8} N$

Explanation:

The magnitude of the gravitational force between two objects is given by the equation:

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

$m_1, m_2$ are the masses of the two objects

r is the separation between the objects

For the two objects in this problem:

$m_1 = 20 kg\\m_2 = 100 kg$

And their distance is

r = 2.6 m

So, the gravitational force between them is

$F=\frac{(6.67\cdot 10^{-11})(20)(100)}{2.6^2}=1.97\cdot 10^{-8} N$
