Find g value And explain how

1.	Find g value And explain how
Answer» 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\xa0N m2\xa0kg-2, mass of the earth,M = 6 × 1024\xa0kg, and radius of the earth,R = 6.4 × 106\xa0m.\xa0g=G M/R2 6.7 10-11\xa0N m2\xa0kg-2\xa06 1024\xa0kg / (6.4 106\xa0m)2 = 9.8 m s–2.Thus, the value of acceleration due to gravity of the earth, g = 9.8 m s–2.
