Vedclass · Answer

(D) $(1)$ Planck's constant $(h)$: $E = h
u \implies [h] = [E]/[
u] = [ML^2 T^{-2}] / [T^{-1}] = [ML^2 T^{-1}]$. This matches (iii).$(2)$ Gravitational constant $(G)$: $F = G(m_1 m_2)/r^2 \implies [G] = [F r^2] / [M^2] = [MLT^{-2}][L^2] / [M^2] = [M^{-1} L^3 T^{-2}]$. This matches (iv).$(3)$ Bulk modulus $(B)$: $B = 	ext{Stress} / 	ext{Strain} = [ML^{-1} T^{-2}] / [M^0 L^0 T^0] = [ML^{-1} T^{-2}]$. This matches $(i)$.$(4)$ Coefficient of viscosity $(\eta)$: $F = \eta A (dv/dx) \implies [\eta] = [F] / ([A][dv/dx]) = [MLT^{-2}] / ([L^2][LT^{-1}/L]) = [MLT^{-2}] / [L^2 T^{-1}] = [ML^{-1} T^{-1}]$. This matches (ii).Therefore, the correct matching is $(1)$-(iii), $(2)$-(iv), $(3)$-$(i)$, $(4)$-(ii). Hence, option $(d)$ is correct.

List-$I$	List-$II$
$(1)$ Planck's constant	$(i)$ $[ML^{-1} T^{-2}]$
$(2)$ Gravitational constant	(ii) $[ML^{-1} T^{-1}]$
$(3)$ Bulk modulus	(iii) $[ML^2 T^{-1}]$
$(4)$ Coefficient of viscosity	(iv) $[M^{-1} L^3 T^{-2}]$
