The dimensions of Stefan-Boltzmann's constant $\sigma$ can be written in terms of Planck's constant $h$, Boltzmann's constant $k_B$ and the speed of light $c$ as $\sigma=h^\alpha k_B^\beta c^\gamma$. Here,
$\alpha=3, \beta=4$ and $\gamma=-3$
$\alpha=3, \beta=-4$ and $\gamma=2$
$\alpha=-3, \beta=4$ and $\gamma=-2$
$\alpha=2, \beta=-3$ and $\gamma=-1$
The dimensions of physical quantity $X$ in the equation Force $ = \frac{X}{{{\rm{Density}}}}$ is given by
Why concept of dimension has basic importance ?
If $A$ and $B$ are two physical quantities having different dimensions then which of the following can't denote a physical quantity?
If energy $(E),$ velocity $(V)$ and time $(T)$ are chosen as the fundamental quantities, the dimensional formula of surface tension will be
