Question

Calculate the value of acceleration due to gravity on moon. Given mass of moon = 7.4 × 10²² kg. radius of moon = 1740 km.

Answer 1

g = \(\frac{GM}{R^2}\)

= \(\frac{6.7 \times 10^{-11} \times 7.4 \times 10^{22}}{(1.740 \times 10^6)^2}\)

= 1.63 ms²

The acceleration due to gravity = 1.63 ms^-2
