Solution
The phenomenon of a comb attracting small bits of paper when run through dry hair is due to the interaction between the comb and the paper. Here are the step-by-step explanations:
-
The comb is made of a material that is a good conductor of electricity. This means that it can easily transfer electric charges.
-
The small bits of paper are also good conductors of electricity. This means that they can easily transfer electric charges as well.
-
When the comb is run through dry hair, it rubs against the hair and picks up some electric charges from the hair. This process is known as triboelectric charging.
-
The charged comb then comes into contact with the small bits of paper. The electric charges on the comb induce a polarization effect on the atoms in the paper.
-
This polarization effect causes the atoms in the paper to rearrange their charges, creating temporary positive and negative regions within the paper.
-
The temporary positive regions in the paper are attracted to the negatively charged comb, while the temporary negative regions are repelled.
-
As a result, the small bits of paper are attracted to the comb and stick to it.
It is important to note that the phenomenon described above is not due to the comb possessing magnetic properties. Instead, it is a result of the interaction between the charged comb and the polarized atoms in the paper.
