Vedclass · Answer

(A) The formula for resistivity is $\rho = \frac{R \cdot A}{l}$.Here,the dimension of resistance $R$ is $[M{L^2}{T^{ - 1}}{Q^{ - 2}}]$.The dimension of area $A$ is $[L^2]$.The dimension of length $l$ is $[L]$.Substituting these into the formula:$[\rho] = \frac{[M{L^2}{T^{ - 1}}{Q^{ - 2}}] \cdot [L^2]}{[L]} = [M{L^3}{T^{ - 1}}{Q^{ - 2}}]$.Thus,the given dimension corresponds to resistivity.

$M{L^3}{T^{ - 1}}{Q^{ - 2}}$ is the dimension of:
