Final answer:
The magnitude of the force can be calculated using Equation 11.2.
Step-by-step explanation:
The magnitude of the force can be calculated using Equation 11.2. The velocity in this question has three components. The z-component of the velocity can be neglected as it is parallel to the magnetic field and generates no force. The magnitude of the force is calculated by finding the magnitude of the x and y components of the velocity. The angle between the velocity in the xy-plane and the magnetic field in the z-plane is 90 degrees. Therefore, the force is calculated to be 1.7 × 10⁻¹⁴ N.
