Solution
The correct option is C Assertion is correct but Reason is incorrect Gauss's law is the easiest way of calculating the electric fields for the symmetrical structure of body such as spherical, cylindrical symmetry etc. So it is valid for any type of charge distribution. For dipole, filed is calculated using superposition principle. Ans:(C)
