Final Answer:
Water is poured into a right cylindrical tank until it reaches equilibrium (B).
Step-by-step explanation:
When water is poured into a right cylindrical tank, it will continue to fill the tank until it reaches equilibrium, which is when the force due to gravity pulling the water down is balanced by the opposing force exerted by the water at the bottom of the tank. At this point, the water level stabilizes, and the system is in equilibrium. This occurs when the weight of the water above a certain level equals the pressure force at that level, preventing further net flow of water into the tank.
According to Archimedes' principle (C), the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. In the context of a cylindrical tank being filled with water, this principle is relevant when the tank reaches equilibrium. The buoyant force acting on the water inside the tank counteracts the gravitational force pulling the water downward, leading to a state of equilibrium. Options A, D are not accurate in this context; the tank will overflow (A) if the volume exceeds the tank's capacity, and buoyancy is indeed affected during the process.
Understanding the dynamics of fluid equilibrium, Archimedes' principle, and the interplay between gravity and buoyancy provides a comprehensive explanation of the behavior of water poured into a right cylindrical tank. The process continues until equilibrium is reached, at which point the forces are balanced, and the water level stabilizes.
