Question
The figure illustrates three scenarios where a positively charged particle moves with a certain velocity through a uniform magnetic field, experiencing a magnetic force. For each scenario, determine if the orientations of the vectors are physically reasonable.

**Diagram Analysis:**

- **Situation (a):**
  - A green cross denotes the magnetic field (\(\vec{B}\)), oriented into the page.
  - The velocity (\(\vec{v}\)) vector is shown in red, pointed towards the top-right.
  - The magnetic force (\(\vec{F_B}\)) is in purple, pointing horizontally to the left.

- **Situation (b):**
  - A green dot represents the magnetic field (\(\vec{B}\)), oriented out of the page.
  - The velocity (\(\vec{v}\)) vector is in red, pointing towards the top-right.
  - The magnetic force (\(\vec{F_B}\)) vector is in green, pointing horizontally to the right.

- **Situation (c):**
  - The magnetic field (\(\vec{B}\)) vector is in green, pointing diagonally upward to the right.
  - The velocity (\(\vec{v}\)) vector is in red, pointing towards the right.
  - The magnetic force (\(\vec{F_B}\)) vector is in purple, pointing horizontally to the left.

**Question:**

Determine if the vector orientations in each situation are physically reasonable:
- no, yes, no
- yes, yes, no
- yes, no, no
- yes, no, yes
- no, yes, yes
