Explanation

To solve the question, "If a uniform electric field is existing inside a cube, then the net charge enclosed inside the cube is ___," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Electric Flux**:
- Electric flux (Φ) through a surface is defined as the product of the electric field (E) and the area (A) through which it passes, and is given by the equation:
\[
\Phi = \int \vec{E} \cdot d\vec{A}
