Which of the following statements about the universal gravitational constant, G, is true? 

A.

It is fundamental quantity

B.

It has dimension M-¹L³T-²

C.

Its S.I. unit is N m\(^2\)kg

D.

It is a vector quantity

Correct answer is B

The universal Gravitational constant(G) is a scalar quantity as it is not in a particular direction

dimensional formula =M-¹L³T-²

S.I. unit = Nm\(^2\)/kg\(^2\)
