If mass is expressed as $v^{x} d^{y} a^{z}$ where $v$ is velocity; $d$ is density and $a$ is acceleration then the value of $x + y + z$ is

Answer:

Solution:

$m \propto v^{x} d^{y} a^{z}$

$M = (L T^{- 1})^{x} (M L^{- 3})^{y} (L T^{- 2})^{z} = M^{y} L^{x - 3 y + z} T^{- x - 2 z}$

$x + y + z = 6 + 1 - 3 = 4$
