Question
**Problem Description:**

The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.1 cm and a mass of 16 grams and is initially at rest. Starting at time \( t = 0 \), two forces are to be applied tangentially to the rim as indicated, so that at time \( t = 1.3 \) s the disk has an angular velocity of 260 rad/s counterclockwise. Force \( F_1 \) has a magnitude of 0.105 N. What is magnitude \( F_2 \)?

**Diagram Explanation:**

- The diagram shows a disk with two forces, \( \vec{F_1} \) and \( \vec{F_2} \), applied tangentially and in opposite directions.
- \( F_1 \) is directed counterclockwise and \( F_2 \) is directed clockwise.
- The forces are indicated by arrows, showing their direction of application on the rim of the disk.

**Solution Input:**

- Input box for the value of \( F_2 \).
- Dropdown menu to select the unit of measurement (e.g., Newtons, for force).
