![**Understanding Electric Flux Through a Circular Surface**
An electric field has a uniform value (doesn't change with position) that can be described by the following equation:
\[ \vec{E} = \left( A \hat{j} + B \hat{k} \right) \, \text{N/C} \]
where A and B are given by the values below.
- \( A = 1.35 \)
- \( B = 1.80 \)
There is a flat circular surface that is in the x-y plane and centered at the origin point (0,0,0). This surface has a radius of \( 1.65 \) m.
**Task:**
Calculate the magnitude of the electric flux through the surface due to the electric field described above. Your units should be \( \text{Nm}^2/\text{C} \).
**Notes:**
- The electric field vector \( \vec{E} \) is composed of the y-component (\( \hat{j} \)) with magnitude \( A = 1.35 \, \text{N/C} \) and the z-component (\( \hat{k} \)) with magnitude \( B = 1.80 \, \text{N/C} \).
- Since the surface is in the x-y plane, the vector normal to this surface (\( \vec{A} \)) points in the z-direction.
To understand the electric flux (\( \Phi_E \)) calculation, consider the following step:
1. The electric flux through a surface is given by the dot product of the electric field vector \( \vec{E} \) and the area vector \( \vec{A} \):
\[\Phi_E = \vec{E} \cdot \vec{A}\]
2. For a circular surface with radius \( r = 1.65 \) m in the x-y plane, the area vector \( \vec{A} \) has a magnitude equal to the area of the circle and points in the positive z-direction (\( \hat{k} \)):
\[
A = \pi r^2 = \pi (1.65)^2 \approx 8.55 \, \text{m}^2
\]
Therefore, \( \vec{A} = 8.55 \hat{k} \, \text{m}^2](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8cdc3187-c2c6-40c5-83e0-80ec87f2e7ff%2F04554d52-2843-4b6f-99c9-8221b30ecedb%2Fbzctl22_processed.png&w=3840&q=75)
