Question

Verify Archimedes principal of buoyancy with an activity. For the activity, you are provided with a piece of stone, a rubber string and a container filled with water​

Answer 1

First of Jill, tie up the stone with the rubber string and hold it against a scale fixed on a wall. Put a mark on the elongated rubber string when stone is tied.Repeat this experiment but this time suspend the stone in a beaker, filled with water. Now, compare the markings. Explanation As the buoyant force is acting on the stone in upward direction, due to this, gravitational pull decreases and in turn, the stretch of the rubber is lost.
