Vedclass · Answer

(B) $1$. Thermal conductivity $(K)$: From $Q = \frac{KA(T_2 - T_1)t}{d}$,we get $[K] = [M^{1} L^{1} T^{-3} K^{-1}]$. This is correct.$2$. Potential $(V)$: $V = \frac{W}{q}$. $[V] = \frac{[M^{1} L^{2} T^{-2}]}{[A^{1} T^{1}]} = [M^{1} L^{2} T^{-3} A^{-1}]$. The given option $B$ states $[M^{1} L^{2} T^{3} A^{-1}]$,which is incorrect.$3$. Permeability of free space $(\mu_{0})$: From $F = \frac{\mu_{0} I_1 I_2 L}{2\pi d}$,we get $[\mu_{0}] = [M^{1} L^{1} T^{-2} A^{-2}]$. This is correct.Therefore,option $B$ is the incorrect statement.
