Question

If two balls made of different materials having different weights but equal volumes are fully immersed in a liquid, they will experience

• A. Equal buoyant force
• B. Unequal buoyant force
• C. No force
• D. All of the above

Answer 1

The correct option is A Equal buoyant force

According to Archimedes Principle, the magnitude of buoyant force experienced is equal to the weight of liquid displaced by it by being placed in it and also its magnitude does not depend on the nature of the solid object.

Hence $F_B=V_{immersed}\rho g$

where $\rho$ is the density of liquid in which the balls are kept, equal in this case and also the immersed volumes are same.

Hence the buoyant force is equal for both the balls.
