Figure 3 shows a rectangular block of wood with a hollow section (inside) at the
position shown. The block is resting on a horizontal bench

(i) State the effect on the stability of the block when the hollow section is filled with water.
(ii) Explain your answer in (i) above.

Answer:

i) - Stability reduces
ii)- The position of centre of gravity is raised when water is added
because the upper (hollow) section becomes heavy or more massive
