Solution

Solution Steps

Step 1: Understanding the Principle of Buoyancy

The principle of buoyancy, also known as Archimedes' principle, states that a body submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the body. This principle is crucial in understanding how objects behave when submerged in a fluid.

Step 2: Analyzing the Options

Weight of fluid: According to Archimedes' principle, a submerged object displaces a volume of fluid whose weight is equal to the buoyant force acting on the object. However, this does not mean the object displaces its own weight of fluid unless it is floating.
Volume of fluid: A completely submerged object displaces a volume of fluid equal to its own volume, not its weight.
Density of fluid: The density of the fluid is not directly related to the displacement caused by the object. It affects the buoyant force but is not displaced by the object.
All of the above: This option is incorrect as the object does not displace its own weight or density of fluid.
None of the above: This option is incorrect because the object does displace a volume of fluid.
