Answer -

Given -

  • Mass of stone = 40 g = 0.04 kg
  • Mass of boulder = 10 kg
  • Distance b/w them = 20 cm = 0.2 m

To Find -

  • Gravitational force ( in term of G i.e. universal gravitation constant )

Solution :-

We know that,

\sf Gravitational \:force = \frac{GMm}{r^2}

where

  • G is universal gravitation constant.

  • M and m are mass of two objects.

  • r is the distance between them.

Substituting the values -

\sf F = \dfrac{GMm}{r^2}

\sf F = \dfrac{G \times 0.04 \times 10}{(0.2)^2}

\sf F = \dfrac{\cancel{0.04} \times 10 G}{\cancel{0.04}}

\sf F = 10G

Gravitational force between them = 10G
