A quantity $x$ is given by $\left( IF v^{2} / WL ^{4}\right)$ in terms of moment of inertia $I,$ force $F$, velocity $v$, work $W$ and Length $L$. The dimensional formula for $x$ is same as that of
Planck's constant
Force constant
Energy density
Coefficient of viscosity
If $A$ and $B$ are two physical quantities having different dimensions then which of the following can't denote a physical quantity?
if Energy is given by $U = \frac{{A\sqrt x }}{{{x^2} + B}},\,$, then dimensions of $AB$ is
If speed $V,$ area $A$ and force $F$ are chosen as fundamental units, then the dimension of Young's modulus will be :
The dimension of the ratio of magnetic flux and the resistance is equal to that of :
