Choose the correct answer from the options given below:

The dimension of $\sqrt{\frac{\mu_0}{\varepsilon_0}}$ is the same as:

The dimension of angular momentum in mass $(M)$, length $(L)$ and time $(T)$ is

Inductance $L$ can be dimensionally represented as

Turpentine oil is flowing through a tube of length $l$ and radius $r$. The pressure difference between the two ends of the tube is $P$. The viscosity of oil is given by $\eta = \frac{P(r^2 - x^2)}{4vl}$,where $v$ is the velocity of oil at a distance $x$ from the axis of the tube. The dimensions of $\eta$ are
