What is the net flux of the uniform electric field of Q.15 thorugh a cube of side 20cm oriented so that its faces are parallel to the co-ordinate planes ?

Explanation

To solve the problem of finding the net electric flux through a cube in a uniform electric field, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electric Flux**:
Electric flux (Φ) through a surface is defined as the product of the electric field (E) and the area (A) of the surface through which the field lines pass, and it is given by the formula:
\[
\Phi = E \cdot A \cdot \cos(\theta)
