GCE A/L 2015 50th MCQ Explanation, Upthrust Related question.

GCE A/L 2015 50th MCQ Explanation, Upthrust Related question. Upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. An object that is partly, or completely, submerged experiences a greater pressure on its bottom surface than on its top surface. This force is called upthrust. An object in a fluid is displacing some of the fluid. The upthrust force is equal in size to the weight of the fluid displaced by the object. Upthrust is the force exerted by a fluid on an object in upwards direction. That's why up-thrust acts against the weight of an object. We know that Upthrust (U) = weight of the liquid displaced by the submerged part of the body. So U=mg , where m is mass of the body and g is the acceleration due to gravity.
