Question:
Two spherical balls of mass $10 \mathrm{~kg}$ each are placed $10 \mathrm{~cm}$ apart. Find the gravitational force of attraction between them.
Solution:
$\mathrm{F}=\frac{\mathrm{G} m_{1} m_{2}}{r^{2}}$
$\mathrm{~F}=$ Gravitational force between two bodies
$\mathrm{G}=$ Gravitational constant
$\mathrm{m}_{1}, \mathrm{~m}_{2}=$ Masses of the two bodies
$\mathrm{r}=$ Distance between the bodies
Here, $\mathrm{m}_{1}=\mathrm{m}_{2}=10 \mathrm{~kg}$
$\mathrm{Nm} \mathrm{m}^{2} / \mathrm{kg}$
