K.C.S.E Physics Q & A - MODEL 2010PP1QN18

Figure 8 shows a stone of mass 4.0kg immersed in water and suspended from a spring balance with a string. The beaker was placed on a compression balance whose reading was 85N. The density of the stone was 3000kgm^-3 while the density of the liquid Was 800kgm^-3.
Determine the:

(a) volume of the liquid displaced; 
(b) Upthrust on the stone; 
(c) reading of the spring balance; 
(d) reading of the compression balance when the stone was removed from the water
