What determines whether an object floats or sinks in a fluid?

उत्तर
Whether an object floats or sinks is determined by its density. When an object is immersed into a liquid, the liquid exerts an upward force on the object. It is known as upthrust. If the weight is greater than the upthrust, it sinks. But it is less on the empty water bottle and so it floats.
