[amp_mcq option1=”rise until its weight equals the buoyant force” option2=”tend to move downward and it may finally sink” option3=”float” option4=”none of the above” correct=”option2″]
The correct answer is: B. tend to move downward and it may finally sink.
The buoyant force is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. The buoyant force is equal to the weight of the fluid displaced by the object.
If the weight of a body immersed in a fluid exceeds the buoyant force, then the body will tend to move downward and it may finally sink. This is because the weight of the body is greater than the upward force exerted by the fluid, so the body will experience a net downward force.
Option A is incorrect because the body will not rise until its weight equals the buoyant force. The body will continue to sink until it reaches a depth where the buoyant force equals its weight.
Option C is incorrect because the body will not float. The body will sink because the weight of the body is greater than the buoyant force.
Option D is incorrect because the body will not do none of the above. The body will tend to move downward and it may finally sink.
