If time (t), velocity (v), and angular momentum ( $ℓ$ ) are taken as the fundamental units. Then the dimension of mass (m) in terms of $t, v$ and $ℓ$ is :

Options:

Answer:

Solution:

$L = v t$

$L = M (v t)^{2} t^{- 1} = M v^{2} t$

$\Rightarrow M = \frac{L}{v ^{2} t}$

$[m] = [l^{1} t^{- 1} v^{- 2}]$
