To solve the problem, we will use the principle of moments, which states that for a lever in equilibrium, the clockwise moments about the fulcrum are equal to the counterclockwise moments. ### Step-by-Step Solution: 1. **Identify the given values:** - Length of the fire tongs (total length) = 28 cm - Distance from the fulcrum where effort is applied (effort arm) = 7 cm - Mass of the coal = 250 g ...
