What happens when a charged plastic rod is brought close to a charged glass rod?
No reaction is observed.
Why does a charged glass rod attracts a piece of paper?
When a positively charged glass rod is brought to it, paper atoms become polarised, with atoms coming closest to the glass rod with a centre of negative charge. This contributes to the piece of paper becoming drawn to the glass rod.
Which type of electricity is produced when a glass rod is rubbed with a silk cloth?
A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged. (a) The glass rod is attracted to the silk because their charges are opposite.
Why does the glass rod repel when brought closer?
When the negatively-charged rod is brought close to the electroscope, positive charges are attracted to it and negative charges are repelled away from it.
What happens when a charged glass rod is brought close to a neutral pith ball placed on a flat table?
The pith ball is neutral and as the negatively charged rod is brought close, the molecules within the ball are reoriented so their electrons will move away from the negatively charged rod (the electrons crowd the far side of the pith ball.
What would happen if a plastic rod rubbed with fur is brought near the glass rod rubbed with silk?
A plastic rod when rubbed with fur becomes negatively charged and a glass rod when rubbed with silk becomes positively charged.
Why does a charged glass rod?
Since the electrostatic force decreases with distance, the repulsion of like charges is weaker than the attraction of unlike charges, and so there is a net attraction. Thus a positively charged glass rod attracts neutral pieces of paper, as will a negatively charged rubber 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.
When a glass rod is rubbed?
Solution: When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. Glass rod becomes positively charged and silk becomes negatively charged.
What kind of charges are produced on each When I a glass rod is rubbed with silk and II an ebonite rod is rubbed with wool?
(i) Positive charge will be produced on glass rod and negative charge will be produced on silk. The electrons are less tightly bound in glass rod as compared to silk. (ii) Negative charge will be produced on ebonite rod and positive charge will be produced on wool.
Why glass rod is positively charged?
When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons. Now the glass rod has 8 electrons and 10 protons which makes it positively charged.
Why does the charged suspended glass rod show attraction towards the charged Ebonite Rod?
When an ebonite rod is rubbed with fur it starts gaining electrons and therefore obtains negative charge and when glass rod is rubbed with silk cloth it starts losing electrons and therefore obtains positive charge. Therefore, by the law of static electric charges, two opposite charged objects attract each other.
