Question

How does the gravitational force of attraction between two masses depend on the distance between them?

Answer 1

Expression for gravitational force is,

$F=G\frac{m_1{m}_2}{r^2}$

From the above expression gravitational force of attraction between two masses is inversely proportional to the square of distance between them,

i.e. $F\propto \frac{1}{r^2}$
