Question #fda13

Answer 1

As per Law of Universal Gravitation the force of attraction between two bodies is directly proportional to the product of masses of the two bodies. it is also inversely proportional to the square of the distance between the two. That is the force of gravity follows inverse square law.
Mathematically

`F_G prop m_1.m_2`
Also `F_G prop 1/r^2`
Combining the two we obtain the proportionality expression

`F_G prop (m_1.m_2)/r^2`
Follows that

`F_G =G (m_1.m_2)/r^2`
Where `G` is the proportionality constant.
It has a value of `6.67408 xx 10^-11 m^3 kg^-1 s^-2`

From the above expression we see that force of gravitation is not dependent on the medium in which the bodies are placed.

Therefore, there will be no change in the gravitational force.
