A potter's wheel is a uniform solid disk of radius R = 0.300 m and M = 120 kg. It is initially rotating at 12.0 rad/s. The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim exerting a normal force (radially inward) of 68.0 N. The effect of pressing with the rag produces a frictional torque that brings the wheel to a stop. What is the frictional torque that acts on the wheel while it is slowing down?

**Problem Statement:**

A potter’s wheel is a uniform solid disk of radius \( R = 0.300 \, \text{m} \) and mass \( M = 120 \, \text{kg} \). It is initially rotating at \( 12.0 \, \text{rad/s} \). The potter can stop the wheel in \( 6.00 \, \text{s} \) by pressing a wet rag against the rim exerting a normal force (radially inward) of \( 68.0 \, \text{N} \). The effect of pressing with the rag produces a *frictional torque* that brings the wheel to a stop. What is the frictional torque that acts on the wheel while it is slowing down?

**Options:**

- \( -125 \, \text{N} \cdot \text{m} \)
- \( -25.5 \, \text{N} \cdot \text{m} \)
- \( -50.0 \, \text{N} \cdot \text{m} \)
- \( -12.5 \, \text{N} \cdot \text{m} \)
- \( -10.8 \, \text{N} \cdot \text{m} \)
