If net flux through a Caussian surface is zero, then find whether the following statements are correct or not.
The number of field lines entering the surface equals to the number of field lines leaving the surface.

Explanation

To determine whether the statements are correct when the net electric flux through a Gaussian surface is zero, we can follow these steps:

### Step 1: Understand the concept of electric flux
Electric flux (Φ) through a surface is defined by the equation:
\[ \Phi = \frac{Q_{\text{enclosed}}}{\epsilon_0} \]
where \(Q_{\text{enclosed}}\) is the charge enclosed by the surface and \(\epsilon_0\) is the permittivity of free space.
