What charge is acquired by the comb?

If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge.

When a person comb his hair static electricity is sometimes generated by what process?

friction
friction between comb and hair resulting in flow of electrons.

Why the pieces of paper initially attracted by charged comb fly away when they touch it?

SOLUTION: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb. When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper.

Why is a comb negatively charged?

The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it. When you comb your hair with a nylon comb, both the comb and your hair become charged. This is a result of your hairs repelling each other because they are charged.

How will 2 positive charges react?

If two positive charges interact, their forces are directed against each other. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity. The two charges attract each other.

What form of energy is produced by the comb?

With a comb , static electricity is produced.

What refers to electric charge?

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative (commonly carried by protons and electrons respectively). An object with an absence of net charge is referred to as neutral.

How can you explain a comb run through dry hair attracts pieces of paper?

When a comb rubhed with dry hair attracts pieces of paper. This is because the comb induces a net dipole moment opposite to the direction of field. This happens the field due to charge on comb induces dipole moment in paper by tretching or re-orienting molecules of the dielectric.
