APPH12-VLQXVP

A physics student observes a $12.2\text{ kg}$ concrete block located at the bottom of a $3.4\text{ m}^3$ tank filled with water
($\rho = 1000\text{ kg/m}^3$).

What can the student determine about the buoyant force acting on the block?

A

The buoyant force is greater than $120\text{ N}$.

B

The buoyant force is equal to $120\text{ N}$.

C

The buoyant force is less than $120\text{ N}$.

D

Without more information, nothing can be determined about the buoyant force.
