Calculate the acceleration due to gravity at the Earth’s surface if the mass of Earth is

6.0\times10^{24}\,\text{kg}

and its radius is

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

. (Take

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

.) (a)

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

(b)

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

(c)

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

(d)

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