The body will sink to the bottom as it gains a downward velocity and has no force to bring it back up. The weight becomes greater than upwards thrust.
As body is just floating, its density is same as that of the liquid.
If pressed below, it will gain momentum downwards, and continue to sink till bottom.
When the body is slightly pressed, the contraction in volume decreases upthrust, so weight becomes greater than upthrust, body moves down. The upthrust further decreases, since more and more contraction occurs as the body moves down. The body thus, sinks to the bottom.

A body is just floating in a liquid (their densities are equal) If the...
Answer:
When a body is floating in a liquid, it means that the body and the liquid have the same density. This implies that the buoyant force acting on the body is equal to the weight of the body.
Explanation:
1. Initial Floating Position:
- In the initial floating position, the weight of the body is balanced by the buoyant force acting in the upward direction.
- The body is in equilibrium and remains at a certain level in the liquid.
2. Slightly Pressed Down:
- When the body is slightly pressed down, it experiences a downward force.
- This disturbs the equilibrium, and the buoyant force is no longer equal to the weight of the body.
- The body starts to sink due to the excess downward force.
3. Sink to the Bottom:
- As the body sinks, it moves towards the bottom of the liquid.
- The buoyant force acting on the body decreases as it moves deeper into the liquid.
- Eventually, the buoyant force becomes less than the weight of the body.
- Since the downward force is now greater than the upward buoyant force, the body continues to sink until it reaches the bottom of the liquid.
4. No Oscillation:
- The body does not oscillate because there is no restoring force acting on it.
- In oscillation, a restoring force brings the body back to its original position.
- In this case, once the body sinks to the bottom, there is no force that brings it back to the initial floating position.
- Therefore, option 'A' (Start oscillating) is incorrect.
Conclusion:
When a body floating in a liquid is slightly pressed down and released, it will sink to the bottom of the liquid. It will not start oscillating or come back to the same position immediately or slowly. This is because there is no restoring force to bring the body back to its original position.
