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 m2kg
D. It is a vector quantity

Correct Answer:

Option B = It has dimension M-¹L³T-².

Explanation

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 = Nm2/kg2
