Vedclass · Answer

(A) Electric flux $\phi_E$ is defined as the product of the electric field $E$ and the area $A$,given by $\phi_E = E \cdot A$.The unit of electric field $E$ is $N/C$ or $V/m$. The dimensional formula for force is $[MLT^{-2}]$ and for charge is $[IT]$.Thus,the dimension of electric field $E = \frac{[MLT^{-2}]}{[IT]} = [MLT^{-3} I^{-1}]$.The dimension of area $A$ is $[L^2]$.Therefore,the dimensional formula for electric flux $\phi_E = [MLT^{-3} I^{-1}] 	imes [L^2] = [ML^3 T^{-3} I^{-1}]$.Comparing this with the given options,the correct option is $A$.

The dimensional formula for electric flux is $..........$
