A block of iron dropped in a vessel of water, sinks to the bottom. This is because
  • 1

    the weight of the block is less than the weight of the water displaced by the block

  • 2

    the density of water is more than the density of the block

  • 3

    the vessel is not deep enough to allow the block to float

  • 4

    the weight of the water displaced by the block is less the weight of the block

Answer:- 4
Explanation:-

 According to law of flotation, a body floats on the surface of liquid, if the weight of liquid displaced by the body is equals to the weight of the body. On the other hand, a body sinks if weight of liquid displaced by it is less than its own weight.
