Question

What is the S.I unit of universal gravitational constant?

• A. $N{m}^{-2}$
• B. $N{m}^{-2}k{g}^2$
• C. $N{m}^{-2}k{g}^{-2}$
• D. $N{m}^{2}k{g}^{-2}$

Answer 1

The correct option is D

$N{m}^{2}k{g}^{-2}$

S.I unit of $G=\left(\frac{newton\times metr{e}^2}{kilogram\times kilogram}\right)$

$=N{m}^{2}k{g}^{-2}$
