5. Once more, please refer to the figure. This time the charge is 5.11 x 10^-6 C, the magnetic field strength is 4.58 T and the electric field strength is 8.50 x 10^5 N/C. The charge experiences a total force of magnitude 8.50 N as it enters the region. What is its speed as it enters the region?

Transcribed Image Text:The image depicts a charged particle moving through a region where both electric and magnetic fields are present.
**Description:**
1. **Magnetic Field (B):**
- Represented by "X" markings in the region. These symbols indicate that the magnetic field is directed into the plane of the diagram.
2. **Electric Field (E):**
- Shown by vertical downward arrows, indicating the direction of the electric field.
3. **Charged Particle:**
- The black dot represents the charged particle moving with velocity \( v \) towards the right of the diagram.
4. **Forces Acting on the Particle:**
- **Magnetic Force (Fm):** The arrow labeled \( F_m \) pointing upwards shows the direction of the magnetic force acting on the particle due to its motion in the magnetic field.
- **Electric Force (Fe):** The arrow labeled \( F_e \) pointing downwards represents the electric force acting on the particle because of the electric field.
**Explanation:**
In the scenario illustrated, the particle experiences the Lorentz force, which is the combination of electric and magnetic forces. The direction of the magnetic force is determined using the right-hand rule, while the electric force follows the direction of the electric field. The balance or imbalance of these forces determines the net motion of the particle.
