To calculate the value of g, we should put the values of G, M and R in Eq. (9), namely, universal gravitational constant,
G = 6.7 × 10–11 N m2 kg-2, mass of the earth,
M = 6 × 1024 kg, and radius of the earth,
R = 6.4 × 106 m.
g=G M/R2
6.7 10-11 N m2 kg-2 6 1024 kg / (6.4 106 m)2 = 9.8 m s–2.
Thus, the value of acceleration due to gravity of the earth, g = 9.8 m s–2.
