# Two uniform disks have the same radius but different masses: disk \( 1 \) has a mass \( M \), disk \( 2 \) has a mass \( 2M \). What is the ratio of the moment of inertia of the first disk to the second disk?

Two uniform disks have the same radius but different masses: disk \( 1 \) has a mass \( M \), disk \( 2 \) has a mass \( 2M \). What is the ratio of the moment of inertia of the first disk to the second disk?

- **A.** \[ 1:4 \]
- **B.** \[ 1:2 \]
- **C.** \[ 2:1 \]
