Question

when does the body float in water​

Answer 1

Answer:

According to the Archimedes' principle, when a body is partially or fully immersed in water, it displaces water equal to its volume. A body floats in water when its weight is less than that of an equal volume of water. If its weight is same as that of an equal volume of water it will remain afloat.
