Detailed Solution

When the medium between two bodies changes, force of gravitation between them remains same.
“Universal law of gravitation states that force of attraction between two bodies of mass

m_{1}

and

m_{2}

separated by a distance

d

is directly proportional to the product of masses and it is inversely proportional to the square of the distance between them.”
i.e.,

F α m_{1} m_{2}

………………… (i)

F α \frac{1}{d^{2}}

………………………… (ii)
or, combining these, we may write,

F = G \frac{m_{1} m_{2}}{d^{2}}

………………………… (iii)
where,

G

is the gravitational constant.
Therefore from equation (iii) we can say that the force of gravitation between the bodies is independent of the surrounding medium. So, the force of gravitation between them will remain same.
