Question

Explain an activity to show charged particles in matter.

Answer 1

Activity to show charged particles in matter:

1. Take a plastic comb.
2. Comb dry hair with the plastic comb.
3. Place the comb near small pieces of paper.
4. It is observed that the pieces of paper stick to the comb.
5. This is because the comb gets electrically charged and attracts the pieces of paper.
6. This activity indicates that comb (matter) gets electrically charged and exerts attractive forces on the paper pieces.

Thus, the activity shows that matter has charged particles.
