1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution Hello everyone, Suppose, we have a stone tied to one end of a rubber string. We suspend the stone by holding the balance or the string.Then, note the reading on the spring balance. Now, slowly dip the stone in water in a container. Our teacher told that the stone faces buoyancy as soon as it is dipped. When the stone is fully immersed in water, no further decrease in elongation is observed in the string. Please explain why does that happen.
