If speed $(V)$, acceleration $(A)$ and force $(F)$ are considered as fundamental units, the dimension of Young’s modulus will be
${V^{ - 2}}{A^2}{F^{ - 2}}$
${V^{ - 2}}{A^2}{F^2}$
${V^{ - 4}}{A^{ - 2}}F$
${V^{ - 4}}{A^{2}}F$
The dimensions of power are
The potential energy of a particle varies with distance $x$ from a fixed origin as $V = \frac{{A\sqrt x }}{{x + B}}$,where
$A$ and $B$ are constants. The dimensions of $AB$ are
The dimensions of $RC$ is
($C$ and $R$ represent capacitance and resistance respectively)
The quantities $A$ and $B$ are related by the relation, $m = A/B$, where $m$ is the linear density and $A$ is the force. The dimensions of $B$ are of
The dimensional formula of wave number is
