Problem

The Earth–Moon centre-to-centre distance is

3.84\times10^{8}\,\text{m}

. The masses are

M_{\oplus}=6.0\times10^{24}\,\text{kg}

and

M_{\text{Moon}}=7.4\times10^{22}\,\text{kg}

. Approximately how far from Earth’s centre, along the line joining the two bodies, is the point where a spacecraft would feel zero net gravitational force? a)

3.70\times10^{8}\,\text{m}

2.00\times10^{8}\,\text{m}

3.46\times10^{8}\,\text{m}

1.54\times10^{8}\,\text{m}
