Options

A. T T F
B. T F T
C. F T F
D. F T T

Answer

To analyze the statements provided in the question, we will evaluate each statement one by one.

### Step 1: Evaluate Statement 1
**Statement 1:** "In any condition, the electric field inside a conductor is always zero."

- **Analysis:** This statement is not true in all conditions. While it is true that in electrostatic equilibrium, the electric field inside a conductor is zero, there are situations (such as when there is a changing magnetic field or during the process of charging) where the electric field inside a conductor can be non-zero. Therefore, this statement is **false**.

### Step 2: Evaluate Statement 2
**Statement 2:** "Under electrostatic condition, conductor is an equipotential volume."

- **Analysis:** This statement is true. In electrostatic equilibrium, the electric field inside a conductor is zero, which means that all points within the conductor are at the same electric potential. Thus, the conductor behaves as an equipotential volume. Therefore, this statement is **true**.

### Step 3: Evaluate Statement 3
**Statement 3:** "Electric field just outside a conducting surface is (σ)/(2ε₀)."

- **Analysis:** This statement is also true. The electric field just outside the surface of a charged conductor is given by the formula \( E = \frac{\sigma}{\epsilon_0} \), where \( \sigma \) is the surface charge density. However, if we consider the electric field just outside a conductor with a uniform surface charge, the correct expression is \( E = \frac{\sigma}{\epsilon_0} \) directed away from the surface. The factor of 2 mentioned in the statement is incorrect, thus making this statement **false**.

### Conclusion
- **Statement 1:** False
- **Statement 2:** True
- **Statement 3:** False

### Final Answer
The correct evaluation of the statements is:
- Statement 1: False
- Statement 2: True
- Statement 3: False

Thus, the correct answer is **FTT** (False, True, False).
