(a) Figure 6 shows two solids W and X made of the same material and immersed in water.
(i) State with a reason one of the containers experiences a greater upthrust.
(ii) Solid W weighs 12N in air, 2N in water and 4N in another liquid. Determine the density of the other liquid.
(b) Figure 7 shows two identical wooden blocks each of mass 0.2kg suspended in water by two strings M and N.
Given that the upthrust on each block is 3.2N, determine the tension in string;
