(a) Mark accurately the point in liquid L2 that is at the same pressure as point P (1mk)
AT the same level as O in the right limb
(b) Determine the number of times L1 is denser than L2 (2mks)
An object weighs 2.6 N in air and 2.2N when completely immersed in water. Determine the relative density of the object

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

Figure 11 shows a test—tube whose cross-sectional area is 2 cm2 partially filled with lead shot floating vertically in water.
(Take gravitational acceleration as 10 ms-2 and density of water p as 1 g cm3)
