The dimensions of impulse are equal to that of

If velocity of light $c$, Planck’s constant $h$ and gravitational constant $G$ are taken as fundamental quantities, then express length in terms of dimensions of these quantities.

From the following combinations of physical constants (expressed through their usual symbols) the only combination, that would have the same value in different systems of units, is

If $V$ denotes the potential difference across the plates of a capacitor of capacitance $C$, the dimensions of $C{V^2}$are

If $G$ is universal gravitation constant and $g$ is acceleration due to gravity, then dimensions of $\frac{G}{g}$ will be ...................

Let $l, r, c$ and $v$ represent inductance, resistance, capacitance and voltage, respectively. The dimension of $\frac {l}{rcv}$ in $SI\,units$ will be
