The correct Answer is:
To analyze the given assertion and reason, we can break down the problem step by step. ### Step 1: Understanding the Assertion The assertion states that "No net charge can stay in the volume of a metallic object when it is in electrostatic condition. The net charge of a metallic object appears on its outer surface." **Explanation**: In electrostatic equilibrium, charges within a conductor redistribute themselves. Any excess charge will move until it reaches the surface of the conductor. Therefore, the assertion is correct. ### Step 2: Understanding the Reason The reason states that "When a metallic object attains electrostatic condition, then electric field intensity becomes zero everywhere inside the volume of the metallic object." **Explanation**: According to electrostatics, when a conductor reaches electrostatic equilibrium, the electric field inside the conductor becomes zero. This is because any electric field would cause the free charges in the conductor to move, contradicting the condition of electrostatic equilibrium. Hence, the reason is also correct. ### Step 3: Linking Assertion and Reason Now, we need to determine if the reason correctly explains the assertion. **Explanation**: The reason provided explains why the assertion is true. Since the electric field inside the conductor is zero, it implies that there can be no net charge within the volume of the conductor. Thus, the charges must reside on the outer surface. ### Conclusion Both the assertion and the reason are correct, and the reason correctly explains the assertion. ### Final Answer Both the assertion and reason are correct, and the reason is the correct explanation for the assertion. ---

  • Assertion: The net electric field intensity is zero everywhere inside a metallic volume in electrostatic condition. Reason: In case of metals or other conducting materials, there are a plenty of free electrons, which are not bound to any particular nucleus and can move around verywhere inside the metallic volume.

  • Assertion: No net charge can exist in the region where electric field is uniform. Reason: For any type of Gaussian surface selected within the region of a uniform electric field, the angle between electric field intensity and area normal is 90^@ everywhere. Hence, electric flux linked with the selected Gaussian surface is equal to zero. If the net electric flux is zero for some Gaussian surface then according to Gauss's law the net charge enclosed within the surface must be zero.

  • 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.

    What will you observe when the metal top of an electroscope is touched with : a positively charged object ?

    Assertion: A metal object kept in timevarying magnetic field gets cooled. Reason: When metal object is kept inside time-varying magnetic field then due to electromagnetic induction electric current start flowing on the surface.

    Assertion: Two electrically neutral metal spheres in contact are moved closer to a charged object and then separated away from each other using insulating handles in the presence of e charged object, Both the neutral objects acquire equal and opposite charges. Reason: When two metallic objects in contact are brought closer to a charged object then electrons are transferred from one object to the other due to induction phenomenon. If we separate the objects in presence of a charged object then electrons are unable to flow back to the original object.

    STATEMENT-2 : An isolated neutral conductor is given some charge . As it is being charged, an electric field appears in the conductor. and STATEMENT -2 : Under static conditions, the net electric field inside a conductor is zero.

    Assertion: A hollow metallic container closed from all sides can act as a source of black body radiation if maintained at a certain temperature, Reason: All metallic objects act as a black body.
