We have to suspend the bob of a pendulum from a spring balance.
Explanation:
- Then we have to to submerge the entire Bob of the pendulum first in normal water then in the liquid whose density we want to measure that is the ethylated spirit water.
- the results that is found is actually the difference between the actual weight and the upthrust.
- The upthrust ratio of the two readings is actually the ratio of the density of the two medium. We know the density of the water hence the density of the ethylated spirit can be easily calculated
