Question

Explain charging by friction and charging by induction? [3 MARKS]

Answer 1

Each point: 2.5 Mark

1. By rubbing two objects of certain materials, we cause electrons to flow from one object to another, thus creating deficit of electrons in one object, and excess of electrons in another. This causes the bodies to develop charges, and this process is called "Charging by friction."
2. When a charged body, let's say a negatively charged body, is brought close to a neutral body, the positive charges in the uncharged body moves towards the charged body, and the negative charges in the uncharged body will move away from the charged body. This causes a separation of charges in the uncharged body, while the net charge of the body will still be zero. This method is called charging by induction.
