On the Moon the surface acceleration due to gravity is

1.62\,\text{m s}^{-2}

. If the Moon’s radius is

1.74\times10^{6}\,\text{m}

, estimate the mass of the Moon.

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

(a)

7.4\times10^{23}\,\text{kg}

(b)

3.7\times10^{22}\,\text{kg}

(c)

7.4\times10^{22}\,\text{kg}

(d)

1.2\times10^{23}\,\text{kg}
