Question 1 Report
A loaded test-tube which floats upright in water is carefully and slightly depressed and then released. Which of the following best describes the sub-sequent motion of the test-tube?
Answer Details
When the loaded test-tube is depressed and then released, it experiences a restoring force that brings it back to its original position. This restoring force arises from the displaced water that exerts an upward buoyant force on the test-tube.
Since the restoring force acts in the opposite direction to the displacement, the motion of the test-tube is oscillatory, with the test-tube moving back and forth around its equilibrium position.
Therefore, the correct answer to the question is "Oscillatory".
