Answer: When electrified rods are brought near light objects,the rods induce opposite charges on the near surfaces of object as well as on farther side of object. … Thus the electrified road attracts light objects.
Why does a charged rod attracts paper?
H5UUvely Chusu If we take a positively charged glass rod near small pieces of paper, the rod attracts the pieces. … This is because the positively charged rod attracts the electrons of a paper piece towards itself. Some of the electrons accumulate at that edge of the paper piece which is closer to the rod.
Why does an electrified rod attracts light objects such as small pieces of paper even when the paper is neutral What is polarization of charges?
Comb attracts a bits of paper because Comb is charged object and paper is in neutral so, to be charged one must be in neutral and Comb is negative charged as it gains electrons from hair. Since ,when Comb is placed near to a bits of paper then papers get charged due to induction.
Do charged objects attract all metals?
Charged objects attract both metal and paper, in fact they will attract metal more due to the delocalised electrons as opposed to electrons just repelling or attracting within their shells, as the latter doesn’t induce charges, but just distorts them.
Why do bits of paper get attracted to a charged rod rather than getting repelled?
A positively charged rod is brought near a piece of 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.
How does a positively charged glass rod attract?
Paper is a dielectric. When a positively charged glass rod is brought near it, atoms of paper get polarised , with center of negative charge of atoms coming closer to glass rod.
What is electrified rod?
When electrified rods are brought near light objects,the rods induce opposite charges on the near surfaces of object as well as on farther side of object. By induction, the metal sphere will have equal and opposite charged (these charged particles doesn’t lose any of it’s charge in contact).
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 does an Ebonite rod rubbed with fur attracts small pieces of paper?
When an ebonite rod is rubbed with fur the rod gets negatively charged because the friction between the fur and the rod makes the ebonite rod to gain electron from the fur. This is because, electrons in fur are less tightly bound than the electrons in the ebonite rod .
When a charged rod is brought near small bits of paper the small bits will?
Why do charges attract and repel?
If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. 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.
Do positively charged objects attract?
And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence upon each other.
Does electricity attract metal?
Forces can be applied at a distance through magnetism and static electricity. A magnet is an object that can attract some metals like iron. Static electricity can also attract objects without touching them, but it works a bit differently. It can attract and repel due to electrical charges.
How does a positively charged rod attract a neutral object?
Both positive and negative objects attract a neutral object by polarizing its molecules.
Under what conditions do charges attract or repel each other?
Two like charges (positive or negative) repel each other and two unlike charges (one positive and one negative) always attract each other.
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.
