The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. **Assertion:** All the charge in a conductor gets distributed on the whole of its outer surface. **Reason:** In a dynamic system, charges try to keep their potential energy minimum. ### Step-by-Step Solution: 1. **Understanding the Assertion:** - When a conductor is charged, the free charges (electrons) within the conductor move under the influence of electric forces. - In electrostatic equilibrium, these charges will redistribute themselves in such a way that the electric field inside the conductor becomes zero. - This means that the excess charge resides entirely on the outer surface of the conductor. Therefore, the assertion is true. 2. **Understanding the Reason:** - Charges in a conductor experience forces due to electric fields. When these charges are free to move, they will do so until they reach a state where the potential energy is minimized. - The potential energy of a system is minimized when the charges are as far apart as possible, which occurs when they are distributed on the outer surface of the conductor. - Thus, the reason provided is also true as it explains the behavior of charges in a conductor. 3. **Conclusion:** - Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the correct answer is that both statements are true, and the reason is a correct explanation of the assertion. ### Final Answer: Both the assertion and the reason are true, and the reason is a correct explanation for the assertion.
