notes

To calculate the value of g, we should put the values of G, M and R in Eq. `"g" = "GM"/"R"^2`, 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.

=`(6.7 xx 10^-11 "Nm"^2 "kg"^2 xx 6 xx 10^24"kg")/((6.4 xx 10^6 "m")^2)`

= 9.8 ms-2

Thus, the value of acceleration due to gravity of the earth, g = 9.8 m s–2.
