Two rods, one of copper and other of steel, experience the same up thrust when placed in water. Thus, both have – (1) equal volume (2) equal weight (3) equal density (4) equal mass
(1) equal volume Explanation: When a body is placed in water, the upthrust or buoyant force acting on it depends upon the following factors: (1) Volume of the body submerged in the liquid - (V), or volume of the liquid displaced - (V); (ft) Density of the liquid - (d); and (Hi) Acceleration due to gravity In-line.
