If pressure $P$ , velocity $V$ and time $T$ are taken as fundamental physical quantities, the dimensional formula of force is

Options:

Answer:

Solution:

Let $F \propto P^{x} V^{y} T^{z}$ by substituting the following dimensions : $[P] = [M L^{- 1} T^{- 2}]$ $[V] = [L T^{- 1}], [T] = [T]$ and comparing the dimension of both sides $x = 1, y = 2, z = 2$ , so $F = P V^{2} T^{2}$
