Problem

Calculate the magnitude of the gravitational force between two point masses of

6\,\text{kg}

and

4\,\text{kg}

kept

0.20\,\text{m}

apart. (Take

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

.) a)

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

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

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

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