Buoyant Force on a Floating Body


When a body is immersed in a liquid, it experiences an upward force called the buoyant force. This force is equal to the weight of the liquid displaced by the body. The buoyant force acts in the opposite direction to the weight of the body and keeps it afloat.


Calculation of Buoyant Force


The buoyant force can be calculated using the formula:


Buoyant force = weight of liquid displaced


For a floating body, the weight of the liquid displaced is equal to the weight of the body. Therefore, the buoyant force on the body is equal to its weight.


Buoyant force = weight of the body


Example Calculation


Given that the mass of the body is 2kg, we can calculate its weight using the formula:


Weight = mass x gravitational acceleration


Here, gravitational acceleration is approximately 9.8m/s².


Therefore, weight of the body = 2kg x 9.8m/s² = 19.6N


Since the body is floating, the buoyant force on it is equal to its weight. Therefore, the buoyant force on the body is 19.6N.


Conclusion


When a body is immersed in a liquid, it experiences an upward force called the buoyant force. This force is equal to the weight of the liquid displaced by the body. For a floating body, the buoyant force is equal to its weight. Therefore, in this example, the buoyant force on a body of mass 2kg floating in a liquid is 19.6N.

When a body is floating in a liquid then the weight of the body is equal to the buoyant force on the body Buoyant force =Weight of the body mg= 2×9.8=19.6 N.
