The dimensional formula for $r.m.s.$ (root mean square) velocity is
${M^0}L{T^{ - 1}}$
${M^0}{L^0}{T^{ - 2}}$
${M^0}{L^0}{T^{ - 1}}$
$ML{T^{ - 3}}$
The dimensional formula for $r.m.s.$ (root mean square) velocity is
The dimensional formula for the $RMS$ velocity is same as the normal velocity.
So, dimension of $RMS$ velocity is $=\left[ M ^0 LT ^{-1}\right]$
So, dimension of $RMS$ velocity is $=\left[ M ^0 LT ^{-1}\right]$
