In which of the following situations does a body float on a liquid surface?
The answer is: The buoyancy force is greater than the weight of the body.
When an object is placed on a liquid surface, it can actually float due to a phenomenon known as buoyancy. When the buoyant force of the liquid is greater than the weight of the object, it will rise to the surface of the liquid. This is because the liquid exerts an upward force on the body, which is greater than the weight of the body and causes it to float. This phenomenon can be seen in everyday life in objects such as boats and ships, which are able to stay afloat due to their buoyancy.
