**Inclined Plane with Friction Conceptual Question**

*Diagram Explanation:*

The image presents three separate diagrams of a block sliding down inclined planes. The planes are set at different angles: 

1. The top diagram shows an incline with angle \( \theta \).
2. The middle diagram has an incline with angle \( 2\theta \).
3. The bottom diagram features an incline with angle \( 3\theta \).

Each block is subject to a kinetic friction force labeled as \( F_k \), \( F_k^2 \), and \( F_k^3 \), respectively, acting opposite to the direction of motion.

*Problem Description:*

A block slides down three different inclined planes as depicted. The coefficient of kinetic friction, \( \mu_k \), is constant between the block and each of the inclines. The inclines are at angles of \( \theta \), \( 2\theta \), and \( 3\theta \) respectively.

*Question:*

Rank the **magnitude** of the kinetic friction **force**, from greatest to least.

- \( \circ \) F1, F2, F3
- \( \circ \) F3, F2, F1
- \( \circ \) Not enough information is given
- \( \circ \) F1, F2, and F3 are all equal
