Given a uniform electric field `E=2xx10^(3)hati N//C` find the flux of this field through a square of side 20cm, whose plane is parallel to the y-z plane. What would be the flux through the same square, if the plane makes an angle of `30^(@)` with the x axis?

Explanation

To solve the problem, we need to calculate the electric flux through a square in two different scenarios: when the square is parallel to the y-z plane and when it makes an angle of 30 degrees with the x-axis.

### Step 1: Understand the Electric Field and Area Vector
The electric field is given as \( \mathbf{E} = 2 \times 10^3 \hat{i} \, \text{N/C} \). The square has a side length of 20 cm, which we need to convert to meters:
\[ \text{Side length} = 20 \, \text{cm} = 0.20 \, \text{m} \]
