The balls of iron and aluminium of same diameter are dipped in water. ...
The correct answer is The upthrust on both balls will be the same.
Key Points
- The balls of iron and aluminium of the same diameter will have the same volume.
- So, the buoyant force exerted by water on both the balls will be the same.
- Buoyant Force is defined as the upward force exerted by a fluid on the immersed body.
- It is also called upthrust.
Additional Information
- Archimedes’ principle states that when an object immersed in fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid.
- When an object is immersed wholly or partially in a fluid, then there is some apparent loss in its weight. This loss in weight is equal to the weight of the liquid displaced by the body.

The balls of iron and aluminium of same diameter are dipped in water. ...
Explanation:
Upthrust on Iron Ball:
- When the iron ball is dipped in water, it displaces a certain volume of water equal to its own volume.
- The upthrust on the iron ball is equal to the weight of the water displaced by the iron ball.
Upthrust on Aluminium Ball:
- Similarly, when the aluminium ball is dipped in water, it displaces the same volume of water as the iron ball.
- The upthrust on the aluminium ball is also equal to the weight of the water displaced by the aluminium ball.
Comparison:
- Since both balls have the same diameter, they displace the same volume of water.
- Therefore, the upthrust on both balls will be the same.
Therefore, the correct statement is that the upthrust on both balls will be the same.
