Question

Precautions in experiment of determining relative density of a solid using principle of moment & Archimede's principle

Answer 1

Two precautions that should be taken while doing the experiment of

determining density of solid using a spring balance and measuring

cylinder are:

1. Select a spring balance without zero error.

2. When an object is immersed in water, see that it does not touch the walls of the measuring cylinder.

3. while observing the readings of a liquid in measuring cylinder, always look at the lower meniscus of water level for readings.
