Study the diagrams above and use them as guides in carrying out the following instructions
(i) Using the spring balance provided, determine the weight of object of mass M = 50.0g in air Record this weight as W1
(ii)Determine the weight of the object when it iv completely immersed in water contained in a ;beaker at shown in the diagram above Record the weight W2
(iii) Determine the weight of the object when it Is completely immersed in the liquid labelled L Record the weight as W3
(iv) Evaluate U= (W1-W2) and V= (W1 – W3)
(v)Repeat the procedure with the objects of masses M= 1OOg, 15O g, 200 g and 250 g
(vi) In each case, evaluate U= (W1-W2) and V= (W1 – W3)
- Tabulate your readings
- Plot a graph with V on the vertical axis and U on the horizontal axis
- Determine the slopes, of the graph
- State two precautions taken to ensure accurate results
(b) (i) State Archimedes’ principle
(ii) A piece of brass of mass 20.0g is hung on a spring balance from a rigid support and completely immersed in kerosene of density 8.0 x 102 kgm \ Determine the reading on the spring balance.
