**Question:**
If the momentum of the person is \( P \), what is the momentum of the skateboard in the situation shown in the figure?

- \( P \)
- \( 2P \)
- zero
- \(-P\)
- \(-2P\)

**Figure Analysis:**

The figure consists of two parts:

1. **Part (a):**  
   - A stationary person stands on a skateboard.
   - Both the person and the skateboard are at rest on the ground.

2. **Part (b):**  
   - The person is moving to the right with a force, represented by a red arrow pointing in the direction of motion.
   - The skateboard is moving in the opposite direction (to the left) with an arrow indicating its direction.

**Concept Explanation:**

In this situation, the principle of conservation of momentum is applied. When the person starts moving forward (to the right), the skateboard moves in the opposite direction (to the left) to conserve the total momentum of the system. If the momentum of the person is \( P \), the momentum of the skateboard will be \(-P\) to maintain zero net momentum of the system as it was initially at rest.
