Problem

Point masses of

2\,\text{kg}

and

18\,\text{kg}

are placed

0.50\,\text{m}

apart on a straight line. Determine the position(s) on this line, measured from the

2\,\text{kg}

mass, where a test particle would experience zero net gravitational field. Give your answer to two significant figures. Take

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