Question

When a glass rod is rubbed with silk cloth, then what kind of the electric charge produced on the glass rod?

Answer 1

Electric charge:

1. The physical characteristic of matter that causes it to feel a force when exposed to an electromagnetic field is called an electric charge.
2. You can have a positive or negative electric charge (commonly carried by protons and electrons respectively).
3. It will be accomplished by rubbing two materials against one other, during which time electrons will migrate from one substance to the other.

Charging by rubbing:

1. Electrons are transmitted from one body to another when two various insulating materials are rubbed together.
2. Charging by friction is the name given to this process.
3. Electrons are transported from a plastic rod to a piece of cloth, for instance, when the two objects are rubbed together.
4. The outcome is that the fabric is negatively charged and the rod is positively charged.

When a glass rod is brushed with silk clothing, the glass loses electrons quickly, and the silk absorbs electrons from the glass rod. The glass rod becomes positively charged after rubbing, whereas the silk becomes negatively charged.

1. As a result, when glass is rubbed, it takes on a positive charge whereas silk takes on a negative charge.
2. Equal yet opposing charges are produced on both of them.

Hence it can be concluded that

1. Silk cloths: Negatively charged
2. Glass rod: Positively charged
