Section A

[28 marks]

Answer all questions in this section.

The time suggested to complete this section is 60 minutes.

1 The experiment is carried out to study Archimedes principle. A rod which is 10 cmlong is marked at intervals of 1 cm and suspended from the hook of spring balance.The rod is lowered into a liquid as shown in figure 1. The length of rod below theliquid level is measured and the reading on the spring balance is recorded. Theexperiment is started by lowering the rod to a depth of 5.0 cm and the reading on thespring balance, W/N is recorded. The experiment is repeated by lowering the rod todifferent depth, i.e h = 6.0 cm, 7.0 cm, 8.0 cm , 9.0 cm and 10 cm.
