Buoyancy: The Resultant Upward Pressure of Fluid on an Immersed Body
When an object is placed in a fluid, there is a force that the fluid exerts on the object. This force is known as buoyancy. This force is exerted in an upward direction, and it is equal to the weight of the fluid displaced by the object. The concept of buoyancy is important in many areas of science and engineering, including ship design, submarine design, and the design and operation of dams.
Explanation of Options
a) Upthrust: Upthrust is a term that is often used interchangeably with buoyancy. Both terms refer to the upward force that a fluid exerts on an object immersed in it. So, option 'A' is not the correct answer.
b) Buoyancy: The correct answer is option 'B'. Buoyancy is the resultant upward pressure of the fluid on an immersed body. It is a fundamental concept in fluid dynamics and is used extensively in engineering and physics.
c) Centre of Pressure: Centre of pressure is the point on an object where the total force acting on the object can be considered to act. It is the point where the buoyancy force and other forces acting on the object balance each other. While it is related to buoyancy, it is not the same thing. So, option 'C' is not the correct answer.
d) All the above are correct: This option is incorrect because option 'A' and option 'C' are not correct.
e) None of the above is correct: This option is incorrect because the correct answer is option 'B' - Buoyancy.
