Question

4. The mass of the Earth is 6 x 1024 kg. The radius of the Earth is 6.4 x 100 m, and the gravitational
constant 6.7 x 10–11 Nm²/kg?, calculate the value of g.​

Answer 1

Explanation:

we know that

GM = g* R^2

(6.7*10^-11)*(6*10^24) =g*(6.4*10^6)^2

g = (4.02*10^14)/(4.096^10^13)

g= 9.81 m/s^2
