Question

The false statement about the universal gravitational constant (G) among the following is ____.

• A. Its dimensional formula is ${[M}^{-1}{L}^3{T}^{-2}]$
• B. It is a vector quantity
• C. Its value is $6.67X{10}^{-11}$
• D. Its unit is $N{m}^2{kg}^{-2}$ .

Answer 1

The correct option is B It is a vector quantity

The universal Gravitational constant(G) is a scalar quantity as it is not in a particular direction. A vector quantity should possess both magnitude and direction. Hence gravitational constant is a scalar quantity as it does not depend on direction.
