1. **Problem Statement:** A student of mass 60 kg is hanging vertically from a string attached to a ceiling fan mount. We need to find the tension in the string exerted by the student's neck. 2. **Relevant Formula:** The tension $T$ in the string when the student is hanging stationary is equal to the gravitational force acting on the student. $$T = mg$$ where: - $m$ is the mass of the student (60 kg), - $g$ is the acceleration due to gravity (approximately 9.8 m/s$^2$). 3. **Calculation:** Substitute the values: $$T = 60 \times 9.8$$ $$T = 588 \text{ N}$$ 4. **Explanation:** The tension in the string must balance the weight of the student to keep them hanging stationary. The weight is the force due to gravity, calculated by multiplying mass by gravitational acceleration. Therefore, the tension is 588 newtons. **Final Answer:** $$\boxed{588 \text{ N}}$$
