Question

what is the dimension of universal gravitational constant??​

Answer 1

it is a force so it's dimension is

Answer 2

Answer:

Since F = m a = G M m / R^2

a = G M / R^2

Then G = a R^2 / M = (m/s^2) * m^2 / kg = m^3 / (s^2 kg)

You can write this as (kg m / s^2) * (m^2 / kg^2)

Since N (Newton) = kg m / s^2 you have

N m^2 / kg^2 for the units of G
