Answer 2

$\green{\bold{\underline{\underline{Given:}}}}$

• Mass of a body (M) = 12 kg
• Mass of another body (m) = 3 kg
• The distance between them (d) = 12 m

$\purple{\bold{\underline{\underline{To\:find:}}}}$

• Gravitational force between the two bodies (F) = ?

$\red{\bold{\underline{\underline{Solution:}}}}$

We know, Gravitational force = $\frac{GMm}{d²}$

Where, G is also known as gravitation constant. The value of G = 6.67 × 10^-11 Nm² kg^-2

$\implies$ F = $\frac{6.67\:×\:10^-11\:×\:12\:×\:3}{12²}$

$\implies$ F = $\frac{667\:×\:10^-13}{4}$

$\implies$ F = 166.5 × 10^-13 N

$\therefore$ Gravitational force = 166.5 × 10^-13 Newton.

Hope it helped you dear...
