The question is: If an object sinks in the water, then
Correct answer: A. Object is denser than water
- A. Object is denser than water
- B. Water is denser than object
- C. Either a or b
- D. None of these
Explanation
An object sinks in water if its density is greater than the density of water. Density is defined as mass per unit volume.If the object is denser than water, it means that it has more mass packed into the same volume compared to water. This causes the object to experience a greater downward force due to gravity (weight) than the upward buoyant force exerted by the water.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
