Problem

Two point masses

5\,\text{kg}

and

10\,\text{kg}

are placed

0.20\,\text{m}

apart. Taking

G = 6.67\times10^{-11}\,\text{N m}^2\text{kg}^{-2}

, the magnitude of the gravitational force between them is a)

2.5\times10^{-8}\,\text{N}

8.3\times10^{-9}\,\text{N}

8.3\times10^{-8}\,\text{N}

1.7\times10^{-8}\,\text{N}
