Methods of Charging
Methods of Charging: Overview
This topic covers concepts, such as, Charging of a Body by Conduction, Charging of a Body by Induction, Acquisition of Opposite Charges after Rubbing & Charges on Plastic and Wool Cloth after Rubbing etc.
Important Questions on Methods of Charging
Let and are two identical objects of same mass initially are charged electro statically by rubbing against each other. Let has got a positive charge and has got a negative charge, then match column I and column II.
| Column I | Column II | ||
|---|---|---|---|
| (i) | Mass of | a. | Increases |
| (ii) | Mass of | b. | Decreases |
| (iii) | Work function of | c. | Is less |
| (iv) | Work function of | d. | Is more |
What happens when a charged body is brought near an uncharged body?
Can two like charged bodies attract each other explain?
What happens between a charged and uncharged object?
What happens when a plastic rod is rubbed with wool?
What happens when plastic is rubbed with wool?
When a glass rod is rubbed with silk cloth then?
What happen when flannel is rubbed over a glass rod?
What happens when an ebonite rod and silk cloth are rubbed with each other? Explain.
What happens between charged and uncharged object?
Why the electric charge developed on glass rod rubbed with silk cloth is different from the charge developed on ebonite rod rubbed with fur?
When an ebonite rod is rubbed with fur, fur loses electrons and ebonite rod gains electrons.
When an ebonite rod is rubbed with wool, they get oppositely charged due to conduction. Explain
When Ebonite rod is rubbed with fur it acquires_____ charge.
Why does a glass rod when rubbed with silk cloth acquire positive charge and not?
The electric charge developed on glass rod rubbed with silk cloth is different from the charge developed on ebonite rod rubbed with fur.
A glass rod rubbed with silk is brought near the fur rubbed with an ebonite rod. What will be your observation between them?
After rubbing the glass rod with silk cloth, the glass rod becomes positively charged. The silk cloth becomes negatively charged.
