Assertion (A) The ships of iron and the boats of wood float in water but the nails iron sink.
Reason (R) The special design and shape of the ship and the boat through which weight of displaced water are more than the weight of the ship and boat, due to which more force of buoyancy becomes operative and the ships or boats floats. But the weight of the water displaced by the nails is less than the weight of nails that is why nails sink.
