Question

How do you find the mass of the earth?

Answer 1

Hey people,

We know that acceleration due to gravity g is 9.8 m/s²

We have  Universal Gravitational Constant G= 6.67 *10⁻¹¹ N m²/kg²

We have radius of the earth as R= 6.4 *10⁶ m

Now, we know that g= GM/R²

By putting the given values, we get mass of the earth as M= 5.9 *10²⁴ kg

Hope, this helps :)
