Question

whan a leaf falls on water , it floats , but a fruit when dropped into water sinks . explain .​

Answer 1

The leaf floats on water when dropped, because it is lighter than a fruit, and according to the Buoyancy effect, there is an invisible net kind-of thing on the water surface, which resists if the thing dropped is light but it breaks and the thing drops down. Hence a fruit sinks when dropped but a leaf floats.
