Question

why does an object float or sink when placed on the surface of water?​

Answer 1

• An object floats when the weight force on the object is balanced by the upward push of the water on the object. The upwards push of the water increases with the volume of the object that is under water; it is not affected by the depth of the water or the amount of water.

Answer 2

Explanation:

* An object sinks in water if its density is greater than that of water. * An object floats in water if its density is less than that of water.
