​

Answer 1

Answer:

SI units, G has the value 6.67 × 10-11

Newtons kg-2 m2.

Answer 2

The S.I. unit of gravitational constant is $NKg^{-2} m^{2}$.

Explanation:

• SI system is preferred in most places around the world, because it is easy to use a single standard in communicating scientific data without vocabulary confusion across the globe.

• The formula that explains Newton's laws of gravitation is given by:

                                                   $F=\frac{GMm}{r^{2} }$  

      Upon rearranging the given formula to obtain the value of G:                        

                                                 $G=\frac{Fr^{2} }{Mm}$

• The S.I unit of Force (F) is Newton or N, mass (M or m) is Kg and distance (r) is m.

• Therefore, the S.I unit of G becomes $NKg^{-2} m^{2}$

Final Answer:  

The S.I unit of gravitational constant "G" becomes $NKg^{-2} m^{2}$.
