The correct Answer is:
To analyze the statements provided in the question, we will evaluate each one step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** "In any condition, the electric field inside a conductor is always zero." - **Analysis:** This statement is false. The electric field inside a conductor is zero only under electrostatic conditions, where there is no movement of charge (no current). If there is a current flowing through the conductor, the electric field inside the conductor is non-zero due to the presence of a potential difference that drives the current. ### Step 2: Evaluate Statement 2 **Statement 2:** "Under electrostatic condition, the conductor is an equipotential volume." - **Analysis:** This statement is true. In electrostatic conditions, the electric field inside a conductor is zero, which implies that the potential difference (V) across any two points inside the conductor is also zero. Therefore, the potential remains constant throughout the volume of the conductor, making it an equipotential volume. ### Step 3: Evaluate Statement 3 **Statement 3:** "Electric field just outside a conducting surface is (σ)/(2ε₀)." - **Analysis:** This statement is true. The electric field just outside a conducting surface with surface charge density σ is given by the formula E = σ/(2ε₀). This is derived from Gauss's law, which states that the electric field due to a charged surface is proportional to the surface charge density. ### Conclusion - **Final Evaluation of Statements:** - Statement 1: False - Statement 2: True - Statement 3: True Thus, the correct answer is that Statement 1 is false, while Statements 2 and 3 are true. ### Summary of Answers: - Statement 1: False - Statement 2: True - Statement 3: True
