Question

Find the mass of earth given that g = 9.8 ms-2, radius
of earth is 6.4 x 106 m and G = 6.66 x 10-11 N m^2 kg^-2​

Answer 1

Answer:

g=9.8 m/s^2

R= 6.4×10^6 m

G= 6.66×10^-11 Nm^2/kg^2

Mass of Earth = M = ?

We know that,

g= GM/R^2

Putting the value,

gR^2/G = M

9.8×(6.4×10^6)^2 / 6.66×10^-11 = M

60.271 = M
