9. Assertion When a charged body is brought near to an uncharged conducting body equal and opposite charge is induced on the nearer surface of the conducting body. Reason Net electric field inside the conductor is zero.
heyy bud..explain it briefly
Answers
Answer:
The assertion is false but the reason is true.
Whenever any charged body is brought near the uncharged body then, the uncharged body tends to attain the charge. This is called the conduction effect.
When 2 bodies are placed together then the uncharged body will always acquire the same charge. If we place a positively charged body near the uncharged one then the uncharged body will be positively charged.
But if you slightly move the charged body away then the opposite charges will come closer to the nearby surface and the same charges will move apart.
Now with the help of earthing, we can make the body get charged according to our desire.
This is called the induction and conduction effect.

Answer: The assertion and reason provided are correct. When a charged body is brought near an uncharged conductor, the electric field produced by the charged body induces an equal and opposite charge on the surface of the conductor closest to it.
Electrostatic induction is the phenomenon by which an electric field produced by a charged body can induce an opposite charge on a nearby conductor. This occurs because the electric field produces a difference in potential between the two sides of the conductor, and this causes electrons to flow from one side of the conductor to the other until the electric field inside the conductor is neutralized.
The reason why the net electric field inside a conductor must be zero is that a conductor is an object that allows electrons to move freely within it. When an electric field is present within the conductor, it causes electrons to flow, and this flow of electrons creates an opposing electric field that neutralizes the original field. This process continues until the net electric field within the conductor is zero, which means that there is no longer any force acting on the electrons and they are in a state of electrostatic equilibrium.
When a charged body is brought near an uncharged conductor, the electric field produced by the charged body induces an equal and opposite charge on the surface of the conductor closest to it. The induced charges on the surface of the conductor redistribute themselves so as to cancel out the electric field inside the conductor. This process occurs until there is no longer any net electric field within the conductor and the conductor is in a state of electrostatic equilibrium.
It is important to note that this induction of charges is only temporary, and if the charged body is removed, the induced charges on the conductor will eventually return to their original state, as the electrons will flow back to their original positions. This process of electrostatic induction is a fundamental concept in the study of electricity and plays a crucial role in many applications, including electrical generators and transformers.
