The correct Answer is:
To solve the given assertion and reason problem, we will analyze both statements and determine their validity. ### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "The net electric field intensity is zero everywhere inside a metallic volume in electrostatic condition." - In electrostatic conditions, charges in a conductor redistribute themselves until they reach equilibrium. Inside a conductor, the electric field must be zero; otherwise, free electrons would continue to move. 2. **Understanding the Reason**: The reason provided is that "In case of metals or other conducting materials, there are plenty of free electrons, which are not bound to any particular nucleus and can move around everywhere inside the metallic volume." - This statement is true. Metals have free electrons that can move throughout the material. When an external electric field is applied, these free electrons move to the surface of the conductor, leading to a redistribution of charge. 3. **Connecting Assertion and Reason**: - The assertion is true because the electric field inside a conductor in electrostatic equilibrium is zero. - The reason is also true and provides a valid explanation for the assertion. The movement of free electrons to the surface of the conductor results in the cancellation of electric fields within the conductor, leading to a net electric field of zero. 4. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that both statements are correct, and the reason is the correct explanation for the assertion. ### Final Answer: Both the assertion and reason are true, and the reason is the correct explanation for the assertion. ---

Assertion: Not net charge can stay in volume of metallic object when the same is in electrostatic condition. Net charge of metallic object appears on its outer surface. Reason: When a metallic object attains electrostatic condition then electric field intensity becomes zero everywhere inside the volume of the metallic object.

Assertion: We can protect electrically sensitive instruments by keeping them inside a metallic box. Reason: Conductors can maintain a uniform electric field inside them.

Assertion: Free electrons can move freely everywhere inside metallic volume and free electrons reaching near the surface escape from the metal and new electrons from surrounding enter inside the metal to compensate for these lost electrons. Reason: In natural state, matter is electrically neutral, hence the number of protons in nucleus is always equal to the number of electrons revolving around the nucleus.

Assertion: When a dielectric material is kept inside some external electric field then the net electric field intensity inside the volume of dielectric is always less than external electric field intensity. Reason: In a normal state, polar molecules of dielectric material are randomly oriented and their net electric field remains zero. If we apply electric field on a dielectric material then the polar molecules experience torque and gets aligned along its direction.

Assertion: There is a solid metallic sphere. When some charge is given to the sphere then it is found that charge gets distributed uniformly on the outer surface of the sphere. Reason: Electric field intensity inside the metallic volume is zero everywhere in electrostatic condition, hence for Gaussian surface of any shape inside the metallic volume, electric flux will always be zero. According to Gauss's law, the net enclosed charge is zero.

Assertion : Free electrons inside a metal are free to move out of the metal. Reason : Free electrons inside conductor do not need additional energy to get out of the metal.

Assertion : There is no current in the metals in the absence of electric field. Reason : Motion of free electron are randomly.

Assertion: Through large number of free electron are present in the metal, yet there is no current in the absent of electric field. Reason: In the absence of electric field, electrons move remdomly in all directions

Assertion. A metallic shield in the form of a hollow shell, can be built to block an electric field. Reason. In a hollow spherical shell, the electric field inside is not zero at every point.

Assertion:- Any arbitrary displacement of charges inside a shell does not introduce any change in the electrostatic field of the outer space. Reason:- A closed conducting shell divides the entire space into the inner and outer parts which are completely independent of one another in respect of electric fields.
