**Problem Statement:**

The figure below shows a uniform electric field of magnitude \( E = 480 \, \text{N/C} \) making an angle of \( \phi = 66.5^\circ \) with a flat surface of area \( A = 3.10 \, \text{m}^2 \). What is the magnitude of the electric flux through this surface (in \( \text{N} \cdot \text{m}^2/\text{C} \))?

**Diagram Explanation:**

- The diagram depicts a flat rectangular surface with lines representing a uniform electric field, denoted as \( \vec{E} \).
- The electric field lines intersect the surface at an angle, \( \phi = 66.5^\circ \), from the normal (perpendicular) to the surface.
- The angle is clearly marked between the normal to the surface and the direction of the electric field \( \vec{E} \).

To calculate the electric flux (\( \Phi \)), use the formula:

\[
\Phi = E \cdot A \cdot \cos(\phi)
\]

where
- \( E = 480 \, \text{N/C} \)
- \( A = 3.10 \, \text{m}^2 \)
- \( \phi = 66.5^\circ \)

Expert Solution
Step 1: Formula for electric flux through a surface

The electric flux (straight capital phi subscript E) through a surface is given by the formula:

straight capital phi subscript E equals E times A times cos invisible function application not stretchy left parenthesis theta not stretchy right parenthesis

where:
E is the magnitude of the electric field,
A is the area of the surface, and
theta is the angle between the electric field and the normal to the surface.
