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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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\(^2\)
