What happens when a charged comb is brought near tiny pieces of paper?
Answer : When a charged comb is brought near a small piece of paper, it attracts the piece because of induction. … Thus when a charged comb is brought near a piece, the charges at the pointing end of the comb attracts the opposite charge on the piece of the paper which were introduced due to induction.
How a charged comb can attract neutral pieces of paper does this contradict Coulomb’s law?
A charged object can attract a neutral material
A charged object such as a plastic comb (e.g. charged by rubbing against you hair) can attract a piece of paper which is neutral by inducing electric dipoles in the paper; the 1/r2 dependences of Coulomb’s Law => net attraction.
Why does a charged rod attracts paper?
When the positively charged rod is brought near the neutral paper, it induces a negative charge on the side of the paper nearer to the rod. Since unlike charges attract each other, the paper will be attracted to the rod. … The paper remains attracted to the rod.
When a charged comb is brought near their flowing stream?
When the charged comb is brought near water, the water molecules reorient themselves such that opposite charges align themselves towards the comb. As we know that unlike charges attract, the water-flow bends towards the comb.
When a charged comb is brought near their flowing steam?
when a charged comb is brought near their flowing stream. how many of them show deflection as per following figure ? solution : only polar molecule in the liquid form deflects from its path in the presence of charged comb.
Why does a plastic comb rubbed with dry hair attract bits of paper?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.
How Electric forces and electric fields interact in pieces of paper attracted by comb?
A comb is charged with static electricity by combing hair. In turn, the charged comb attracts pieces of paper. … Thus, the attractive force on the paper molecules’ nuclei (which are closer) is stronger than the repulsive force on the paper molecule’s electrons (which are farther).
Why did the bits of paper stick to the balloon?
When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive. Since positive and negative attract, the paper moves toward the balloon. The negatively charged balloon attracts the paper.
Why do charged and neutral objects attract?
A neutral object will attract both a positive and a negative charge. This is because in some objects, electrons are free to move and transform the charge from positive to negative. These attractive and repulsive forces are exactly that, forces. A charged object has an effect on other charged objects around it.
