**Question:**

1. What is the direction of the velocity of a negative charge that experiences the magnetic force shown in each of the three cases shown in the figure, assuming it moves perpendicular to \(B\)?

**Explanation of Diagrams:**

The figure shows three different scenarios labeled (a), (b), and (c) that illustrate the interaction of a negative charge with a magnetic field (\(B\)). The diagrams use the right-hand rule to determine the direction of force (\(F\)) on a negative charge moving perpendicular to the magnetic field lines (\(B\)):

- **Diagram (a):**
  - Depicts a magnetic field (\(B_{\text{out}}\)) represented with dots, indicating the field is coming out of the page.
  - The magnetic force (\(F\)) is directed upwards.

- **Diagram (b):**
  - Illustrates a uniform magnetic field directed to the right.
  - The magnetic force (\(F\)) is pointing upwards.

- **Diagram (c):**
  - Shows a magnetic field (\(B_{\text{in}}\)) represented with crosses, indicating the field is going into the page.
  - The magnetic force (\(F\)) is directed to the left. 

In all cases, the negative charge moves perpendicular to the magnetic field lines, and the directions are determined using the right-hand rule, adjusting for the negative charge by reversing the standard force direction.
