(i) State Guass. law.
(ii) In an electric dipole, at which point is the electric potential zero?

Explanation

### Step-by-Step Solution:

**(i) State Gauss's Law:**

Gauss's Law states that the net electric flux (Φ) through any closed surface is equal to the net charge (Q) enclosed within that surface divided by the permittivity of free space (ε₀). Mathematically, it can be expressed as:

\[
\Phi = \frac{Q_{\text{inside}}}{\varepsilon_0}
