A stiff wire 46.5 cm long is bent at a right angle in the middle. One section lies along the z axis and the other is along the line y = 2x in the xy plane. A current of 16.5 A flows in the wire-down the z axis and out the line in the æy plane. The wire passes through a uniform magnetic field given by B = (0.318i) T.

Please help me with both parts of this problem, and double check your answers, i have had many issues with tutors in the past giving incorrect answers, and thats of no use to me then
![**Problem 27.7**
**Description:**
A stiff wire 46.5 cm long is bent at a right angle in the middle. One section lies along the z-axis and the other is along the line \( y = 2x \) in the xy-plane. A current of 16.5 A flows in the wire—down the z-axis and out the line in the xy-plane. The wire passes through a uniform magnetic field given by \( \mathbf{B} = (0.318\hat{i}) \) T.
**Part A:**
Determine the magnitude and direction of the total force on the wire.
\[ F = \] __________ N
[Submit] [Request Answer]
**Part B:**
\[ \theta = \] __________ ° below the negative y-axis
---
**Explanation:**
1. **Description of the Stiff Wire:** This part explains the setup of the problem, describing the length of the wire, the sections of the wire, and the direction and magnitude of the current.
2. **Magnetic Field Information:** The uniform magnetic field through which the current-carrying wire passes is defined mathematically as \( \mathbf{B} = (0.318\hat{i}) \) T, where \(\hat{i}\) is the unit vector in the x-direction.
3. **Problem Breakdown:**
- **Part A:** The task is to determine the total force (both magnitude and direction) on the current-carrying wire in the magnetic field.
- **Part B:** After finding the force in Part A, this part requires calculating the angle \( \theta \) of the force with respect to the negative y-axis.
