When a negatively charged conductor is connected to earth,a)No charge ...
Explanation:

When a negatively charged conductor is connected to earth, electrons flow from the conductor to the earth. This can be explained by the following points:

- Electric Potential: The negatively charged conductor has an excess of electrons, which creates an electric potential. This electric potential is the difference in electric potential between the conductor and the earth.

- Electric Field: The electric potential difference between the conductor and the earth creates an electric field. The electric field is a force that acts on the electrons in the conductor.

- Electron Flow: The electric field causes the electrons in the conductor to flow towards the earth. This is because the electric field is stronger at the point where the conductor is connected to the earth.

- Neutralization: As the electrons flow from the conductor to the earth, the negative charge on the conductor decreases. Eventually, the charge on the conductor becomes zero, and the conductor is said to be neutralized.

- Conservation of Charge: The total charge in the system remains constant. As the electrons flow from the conductor to the earth, the earth acquires a negative charge. However, since the earth is very large, the negative charge acquired by the earth is negligible.

Conclusion:

In summary, when a negatively charged conductor is connected to earth, electrons flow from the conductor to the earth. This process neutralizes the conductor and conserves the total charge in the system.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Tribo-electric series: The tribo-electric series is a list that ranks materials according to their tendency to gain or lose electrons. The process of electron transfer as a result of two objects coming into contact with one another and then separating is called tribo-electric charging. During such an interaction, one of the two objects will always gain electrons (becoming negatively charge d) and the other object will lose electrons (becoming positively charged). The relative position of the two objects on the tribo-electric series will define which object gains electrons and which object loses electrons.In tribo-electric series, materials are ranked from high to low in terms of the tendency for the material to lose electrons. If an object high up on this list (Glass, for exampl e) is rubbed with an object low down on the list (Teflon, for example), the glass will lose electrons to the teflon. The glass will, in this case, become positively charged and the teflon will become negatively charged. Materials in the middle of the list (steel and wood, for example) are items those do not have a strong tendency to give up or accept electrons.If human hair is rubbed with amber, how those will be charged?
