# A splash of knowledge

A 100-gram cylindrical glass is attached to a string that hangs from the ceiling. Then the glass which has a cross-sectional radius of 4 cm and a height of 15 cm is slowly filled with water. If the string breaks when the glass is $$\frac23$$ full, what is the maximum tension in Newtons that the string can support?


Details and Assumptions:

• The acceleration of gravity is $$-9.8\text{ m/s}^2.$$
• The density of water is $$1\text{ g/cm}^3.$$
