You are provided a retort stand, a spring balance, masses, a beaker containing water, another beaker containing a liquid labelled, L, and other necessary apparatus.

(i) Suspend the mass, m = 20 g on the spring balance and measure the weight in air, WA
in Newton.

(ii) Immerse the suspended mass completely in water and measure weight in water, WW
in Newton. Evaluate U1
= WA
- WW
.

(iii) Immerse the suspended mass completely in the liquid L of the same volume with water and measure the weight in liquid WL
. Evaluate U2
= WA
- WL
.

(iv) Repeat the procedure for m = 40g, 60g, 80g, and 100g respectively. In each case, evaluate WA
, WW
, U1
, WL
, U2
.

(v) Tabulate the readings.

(vi) Plot a graph of U1
on the vertical axis and U2
on the horizontal axis starting both axes from the origin (0, 0).

(vii) Determine the slope s of the graph

(viii) Evaluate K = 1s

(ix) State two precautions taken to ensure accurate results.

b(i) State the Archimedes' principle,

(ii) State two differences between density and relative density
explain in detail?
