how did newton find the value of 'g' with the help of inverse square law?
Solution:
Consider a body of mass = m
According to the law of Gravitation ,
F =GMm/r² ,,,,,,,,,,,,,, (1)
Where F is the force of attraction between the body of mass m and the earth.
G= universal Gravitational Constant
r = distance between the center of masses.
Also ,
we know that earth attracts a body with a force given by
F=mg .......(2)
from 1 and 2 , we gt
mg = GMm/r²
or g =GM/r²
Hope this helps You!!!
