6.5 Exercise 11

Avg difficulty 2.5

Earth is not a perfect sphere. Its radius as well as the value of g vary with latitude. (a) Calculate Earth’s mass given the acceleration due to gravity at the North Pole is 9.807 m/s29.807 m /\text{s}^{2} and the radius of the Earth at the pole is 6356.8 km.

(b) Compare this with the accepted value of 5.972×1024kg5.972 \times \text{10}^{\text{24}} \text{kg}.
