The correct Answer is:
To analyze the statements provided, we will evaluate each statement one by one and determine their validity. ### Step 1: Evaluate Statement 1 **Statement 1:** A stationary electric charge produces an electrostatic field, and this field exerts electrostatic force on another charge. - A stationary electric charge indeed creates an electric field around it. The electric field (E) produced by a point charge (Q) at a distance (r) is given by the formula: \[ E = \frac{k \cdot Q}{r^2} \] where \( k \) is Coulomb's constant. This electric field can exert a force on any other charge placed within this field, which can be calculated using: \[ F = q \cdot E \] where \( q \) is the test charge. Thus, Statement 1 is **true**. ### Step 2: Evaluate Statement 2 **Statement 2:** Theoretically, the electric field is found up to infinite distance from a point charge. - The electric field produced by a point charge decreases with the square of the distance (inversely proportional to \( r^2 \)). As the distance \( r \) approaches infinity, the electric field approaches zero but never actually becomes zero. This means that theoretically, the electric field extends to an infinite distance, although its strength diminishes. Therefore, Statement 2 is also **true**. ### Step 3: Evaluate Statement 3 **Statement 3:** An electron is a point charge. - A point charge is defined as a charge that is concentrated at a single point in space with no dimensions. While electrons are often treated as point charges in physics due to their very small size, they are not purely hypothetical; they have mass and charge. However, in the context of classical electrostatics, electrons can be approximated as point charges. The statement is misleading because it implies that the concept of a point charge is purely hypothetical, while electrons are real particles. Hence, Statement 3 is **false**. ### Conclusion - Statement 1: True - Statement 2: True - Statement 3: False The overall conclusion is that the correct option is **True, True, False**. ---
