5\,\text{kg}

and

20\,\text{kg}

are placed

0.20\,\text{m}

apart in vacuum. Calculate the magnitude of the gravitational force between them. (Take

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

.) (a)

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

(b)

1.7\times10^{-7}\,\text{N}

(c)

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

(d)

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