Problem 3: ( $13 \%$ of Assignment Value)
A uniform electric field of magnitude $19.6 \mathrm{~N} / \mathrm{C}$ is parallel to the x axis. A circular loop of radius 24.7 cm is centered at the origin with the normal to the loop pointing $37.4^{\circ}$ above the x axis.
Part (a)
Calculate the electric flux in, newton squared meters per coulomb, through the loop.
\[
\Phi=\square \mathrm{N} \cdot \mathrm{m}^{2} / \mathrm{C}
\]
Solution
Solution Steps
Step 1: Identify Given Values
Electric field magnitude, \( E = 19.6 \, \text{N/C} \)
Radius of the loop, \( R = 24.7 \, \text{cm} = 0.247 \, \text{m} \)
Angle between the normal to the loop and the electric field, \( \theta = 37.4^\circ \)
Step 2: Calculate the Area of the Loop
The area \( A \) of a circular loop is given by:
\[ A = \pi R^2 \]
\[ A = \pi (0.247 \, \text{m})^2 \]
\[ A \approx 0.1917 \, \text{m}^2 \]
Step 3: Calculate the Electric Flux
The electric flux \( \Phi \) through the loop is given by:
\[ \Phi = E \cdot A \cdot \cos(\theta) \]
\[ \Phi = 19.6 \, \text{N/C} \cdot 0.1917 \, \text{m}^2 \cdot \cos(37.4^\circ) \]
\[ \cos(37.4^\circ) \approx 0.796 \]
\[ \Phi \approx 19.6 \cdot 0.1917 \cdot 0.796 \]
\[ \Phi \approx 2.99 \, \text{N} \cdot \text{m}^2/\text{C} \]
