The diagrams show a metal cube suspended from a spring balance before and during immersion
in water.
during
immersion
before
immersion
A reduction in the balance reading occurs as a consequence of the immersion.
Which statement is correct?
A The balance reading will be further reduced if the cube is lowered further into the water.
B The balance reading during immersion corresponds to the upthrust of the water on the cube.
C The forces acting on the vertical sides of the cube contribute to the change in the balance
reading.
D The gravitational pull on the cube is unchanged by the immersion.
