The diagrams illustrate a metal cube hanging from a spring balance before being placed in water and while it is submerged. The balance reading decreases as a result of the immersion. Which statement is correct?
- AThe balance reading will be further reduced if the cube is lowered further into the water.
- BThe balance reading during immersion corresponds to the upthrust of the water on the cube.
- CThe forces acting on the vertical sides of the cube contribute to the change in the balance reading.
- DThe gravitational pull on the cube is unchanged by the immersion.
