Question

If two balls made of iron and aluminium of equal volumes are immersed in a liquid then will they experience equal up thrust ? Justify your answer.

Answer 1

"If two balls made of iron and aluminium of equal volumes are immersed in a liquid then will they experience equal up thrust " is a true statement .

Explanation :

Here two balls are made up of different metals but their volume will be same.
When they are immersed in liquid they experience same upthrust because Upthrust acting on an object depends upon:

---> Volume of object immersed in liquid.
---> density of the liquid in which objects are immersed.

Upthrust does not depend on nature of object.

Answer 2

HEY!!

Iron has higher mass than aluminium and please not the point that volume does not play any role in deciding the weight of the substance.Thus the gravitational force acting on iron will be higher compared to that of aluminium. The iron that possesses more gravitational force experiences less upthrust compared to that of aluminium. There is one more reason for this. The iron having more mass is more denser and the aluminium is less denser  than iron. Objects that are lighter experience more upthrust compared to the objects that are heavier.
