Which of the following statements about the universal gravitational constant, G, is true?
It is fundamental quantity.
It has dimension M-¹L³T-².
Its S.I. unit is N m\(^2\)kg
It is a vector quantity
Пояснення
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\(^2\)
