Answer 2

because of the upthrust force or bouncy exerted by water on body which push the submerged body upward .  upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.


in a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
