Question

A mass of 15 X 10^5 kg is held at a position 9 m away from a mass of 20 X 10^6 kg. What is the gravitational attraction between the two masses?

Answer 1

Answer:

The gravitational attraction between the two masses is 24.7 N.

Explanation:

We have,

Mass of object 1, $m_1=15\times 10^5\ kg$            

Mass of object 2, $m_2=20\times 10^6\ kg$

Distance between masses is 9 m

We know that there exists a gravitational force between masses when they are placed at certain distance. The gravitational force between masses is given by :

$F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{15\times 10^5\times 20\times 10^6}{(9)^2}\\\\F=24.7\ N$

So, the gravitational attraction between the two masses is 24.7 N.
