Stress and surface tension

Vedclass · Answer

(B) $1$. Planck's constant $(h)$ has dimensions $[ML^2T^{-1}]$ and angular momentum $(L = mvr)$ also has dimensions $[ML^2T^{-1}]$.$2$. Stress is defined as force per unit area,$[ML^{-1}T^{-2}]$. Pressure is also force per unit area,$[ML^{-1}T^{-2}]$.$3$. Force is $[MLT^{-2}]$ and tension is a type of force,so it also has dimensions $[MLT^{-2}]$.$4$. Surface tension is defined as force per unit length,$[MT^{-2}]$.Since stress has dimensions $[ML^{-1}T^{-2}]$ and surface tension has dimensions $[MT^{-2}]$,they do not have the same dimensions.

List $I$	List $II$
$P.$ Boltzmann constant	$1.$ $[ML^2T^{-1}]$
$Q.$ Coefficient of viscosity	$2.$ $[ML^{-1}T^{-1}]$
$R.$ Planck constant	$3.$ $[MLT^{-3}K^{-1}]$
$S.$ Thermal conductivity	$4.$ $[ML^2T^{-2}K^{-1}]$

Which of the following pairs does not have the same dimensions?
