Explain how a charged comb can attract small neutral pieces of paper.?

Question

Does this contradict Coloumb's law on electrostatics?

please give details. Thankyou

Answer 1

charged comb polarise the neutral comb. (negative charges, electrons, accumulates on one side and positive on the other to some extent). small small diapoles are formed, which are attracted by the comb.

Answer 2

All charges on bulk matter like comb are created by the transfer of some electrons the lightest charged particle of any matter from one matter to another. Where there is excess it becomes negatively charged and where it is deficient that matter becomes positively charged. Normally matter is electrically neutral. When a charged comb say positively charged,is brought near a small bit of paper, it produces the movement of electrons in the paper towards it. This movement makes the end nearer to comb negatively charged and the other end of paper away from comb becomes positively charged. This phenomenon is called electric induction. There is force of attraction between comb and the near end of paper and force of repulsion between the far end of paper and comb. The force of attraction thus is higher than force of repulsion because the distance be teen the comb and the near end is smaller. The paper being light gets accelerated, gains velocity and move towards the comb showing attraction.

Answer 3

No. The charged comb is starting to be static electrical energy, which has a magnetic belongings, as Farraday and James Clerk Maxwell expected. What motives the charm of the paper to the brush is that section of the electrostatic can charge is transmitted to the paper as magnetic charm.

Answer 4

it creares static electricty

Answer 5

by elecrtrostatic force of induction...........
