Question

Calculate the value of the universal
gravitational constant from the given
data. Mass of the Earth = 6x1024 kg,
Radius of the Earth = 6400 km and
the acceleration due to gravity on the
surface = 9.8 m/s2
[Ans: 6.672x10-N m²Kg22 ]
11​

Answer 1

Step-by-step explanation:

use ma = GMm/r^2

9.8 = G x 6x10^24/6400*6400*10^6 (km into m)

G = 6.67x10^-11
