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

The gravitational attraction between the two masses is 24.7 N.

Step-by-step explanation:

We have,

Mass of object 1,
`m_1=15* 10^5\ kg`

Mass of object 2,
`m_2=20* 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(m_1m_2)/(r^2)\\\\F=6.67* 10^(-11)* (15* 10^5* 20* 10^6)/((9)^2)\\\\F=24.7\ N`

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