Suggest experiments with which you can compare the charges of two electrified bodies

1. Hang two small pieces of cork next to each other on silk threads. We will touch each of them with a piece of electrically charged amber, while some of the electric charge will drain into each of the pieces of the cork. The silk threads to which they are suspended no longer hang vertically, but deviate at an angle. The plugs are now further apart from each other than they were before the charge was received. The same will happen if both pieces of cork are touched by electrically charged pieces of glass. If, however, one piece of cork is touched with the decorated amber and the other with glass, both pieces will be attracted to each other.
2. Comb dry hair with a plastic comb and bring it to small pieces of paper without touching them. The pieces will be attracted to the comb.
3. Rub the ebonite stick with fur and bring it to the torn pieces of paper. The pieces of paper will be attracted to the stick.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
