An object is moving on the circle of radius 7 cm in clockwise directio...
**Given:**

- Radius of the circle = 7 cm
- Speed of the object = 10 cm/s
- Time = 10 sec

**To find:**

- Angle covered by the object in radians in 10 sec

**Formula:**

- Angular speed (ω) = v/r
- Angle covered (θ) = ω * t

**Calculation:**

1. Angular speed (ω) = v/r
- ω = 10 cm/s / 7 cm = 10/7 rad/s

2. Angle covered (θ) = ω * t
- θ = (10/7 rad/s) * 10 s = 100/7 rad

3. Simplifying the angle in radians,
- θ = 14.29 radians (approx.)

**Answer:**

The angle covered by the object in 10 seconds is approximately **14.29 radians**. Therefore, the correct option is c) 14.29 radians.
