The correct Answer is:
To solve the question, we will analyze both statements and their relationship to the principle of a potentiometer. ### Step-by-Step Solution: 1. **Understanding Statement I**: - The first statement claims that "The wire of a potentiometer should be of uniform area of cross-section." - This is essential because a uniform cross-section ensures that the resistance per unit length of the wire is constant. 2. **Understanding Statement II**: - The second statement asserts that "It satisfies the requirement of the principle of a potentiometer." - The principle of a potentiometer states that the potential difference (voltage) across any segment of the wire is directly proportional to the length of that segment, given that the wire has a uniform cross-section. 3. **Linking the Statements**: - If the wire has a uniform area of cross-section, then the resistance is uniform along its length. This uniformity allows the potential drop to be directly proportional to the length of the wire, which is a requirement for the proper functioning of a potentiometer. 4. **Conclusion**: - Since Statement I is true (the wire must have a uniform cross-section) and Statement II is also true (this uniformity satisfies the principle of the potentiometer), we conclude that both statements are correct. - Furthermore, Statement II serves as a correct explanation for Statement I. 5. **Final Answer**: - Both statements are true, and Statement II is the correct explanation for Statement I.

Statement I: A wire of uniform cross-section and uniform resistivity is connected across an ideal cell. Now the length of the wire is doubled keeping volume of the wire constant. The drift velocity of electrons after stretching the wire becomes one-fouth of what it was before stretching the wire. Statement II: If a wire (of uniform resistivity and uniform cross section) of length l_0 is stretched to length nl_0 , then its resistance becomes n^2 times of what it was before stretching the wire (the volume of wire is kept constant in stretching process). Further at constant potential difference, current is inversely proportional to resistance. Finally, drift velocity of free electron is directly proportional to current and inversely proportional to cross-sectional area of current carrying wire.
