If $T = 2 π \frac{ML ^{3}}{3 Yq}$ then find the dimensions of q. Where $T$ is the time period of bar of mass $M$ length $L$ and Young modulus $Y$ .

Answer:

Solution:

$T = 2 π \frac{ML ^{3}}{3 Yq},$ writing dimensions of both the sides, we get $[T] = [\frac{ML ^{3}}{ML ^{- 1} T ^{- 2} q}]^{1/2}$ or $q = [L^{4}]$
