A comb rub through one's dry hair attracts small bits of paper. This is due to
1 comb is a good conductor
2 paper is a good conductor
3 the atoms is the paper get polarised by the charged comb
4 the comb possesses magnetic properties
Explanation:
When a comb rubs through one's dry hair, then comb gets charged and when it comes close to the paper, it induces opposite charges in paper. The field due to the charges in comb, polarises the atoms in the paper. Finally, it attracts the, paper.

Statement A : When charges are shared between any two bodies, no charge is really lost, but some loss of energy does occur. Statement B : During charging or discharging some of the energy is dissipated in the form of heat, sparkling etc.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Charges are conserved by the law of conservation of charges. During charge transfer energy transfer takes place from one form to other form interms of heat sparkling etc. So option (3) is correct.

If a body is charged by rubbing, its weight
1 Remains precisely constant
2 Increases slightly
3 Decreases slightly
4 May increase slightly or may decrease slightly
Explanation:
The weight can be increased slightly, if it acquire negative charge & weight can be decreased slightly, if it acquires positive charge.

Statement A : When a body acquires negative charge, its mass decreases. Statement B : A body acquires negative charge when it loses electrons.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
When electrons are transferred to a body then the charge gain will be \(( - )ve\) and mass of the body increases. So option (4) is correct.
