Vedclass · Answer

(B) $1$. Young's Modulus $(Y) = \frac{	ext{Stress}}{	ext{Strain}} = \frac{[MLT^{-2}]/[L^2]}{[1]} = [ML^{-1}T^{-2}]$. Thus,$(A)-(III)$.$2$. Co-efficient of Viscosity $(\eta)$: From Stokes' Law,$F = 6\pi\eta rv$,so $\eta = \frac{F}{6\pi rv} = \frac{[MLT^{-2}]}{[L][LT^{-1}]} = [ML^{-1}T^{-1}]$. Thus,$(B)-(I)$.$3$. Planck's Constant $(h)$: From $E = h
u$,$h = \frac{E}{
u} = \frac{[ML^2T^{-2}]}{[T^{-1}]} = [ML^2T^{-1}]$. Thus,$(C)-(II)$.$4$. Work Function $(\phi)$: It is a form of energy,so $[\phi] = [ML^2T^{-2}]$. Thus,$(D)-(IV)$.Therefore,the correct matching is $(A)-(III), (B)-(I), (C)-(II), (D)-(IV)$.

List $I$	List $II$
$(A)$ Young's Modulus $(Y)$	$(I)$ $[M L^{-1} T^{-1}]$
$(B)$ Co-efficient of Viscosity $(\eta)$	$(II)$ $[M L^2 T^{-1}]$
$(C)$ Planck's Constant $(h)$	$(III)$ $[M L^{-1} T^{-2}]$
$(D)$ Work Function $(\phi)$	$(IV)$ $[M L^2 T^{-2}]$
