Identify the incorrect statement.
Some physical constants are given in List-$I$ and their dimensional formulae are given in List-$II$. Match the following:
List-$I$ List-$II$ $(1)$ Planck's constant $(i)$ $[ML^{-1} T^{-2}]$ $(2)$ Gravitational constant (ii) $[ML^{-1} T^{-1}]$ $(3)$ Bulk modulus (iii) $[ML^2 T^{-1}]$ $(4)$ Coefficient of viscosity (iv) $[M^{-1} L^3 T^{-2}]$
The correct answer is:
| List-$I$ | List-$II$ |
| $(1)$ Planck's constant | $(i)$ $[ML^{-1} T^{-2}]$ |
| $(2)$ Gravitational constant | (ii) $[ML^{-1} T^{-1}]$ |
| $(3)$ Bulk modulus | (iii) $[ML^2 T^{-1}]$ |
| $(4)$ Coefficient of viscosity | (iv) $[M^{-1} L^3 T^{-2}]$ |
The correct answer is:
