A horizontal uniform meter stick of mass \(0.2\,\text{kg}\) is supported at its midpoint by a pivot point. A mass of \(0.1\,\text{kg}\) is attached to the left end of the meter stick, and another mass of \(0.15\,\text{kg}\) is attached to the right end of the meter stick. A vertical string attached to the left end of the meter stick holds the stick horizontal and at rest. What is the tension in the string?
