Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): A horizontal wire resting on a wooden table carries a current I₁ . A second parallel wire is fixed at a height h directly above it, carrying a current I₂ in the opposite direction. The wire on the table will never lift off the table, regardless of how large the currents are. Reason (R): Parallel wi

Step-by-step solution

Assertion (A) is true: Parallel wires carrying currents in opposite directions repel each other. Since the fixed wire is directly above the wire on the table, the magnetic force on the lower wire acts downwards. Both the magnetic force and gravitational force act downwards, pressing the wire against the table. Thus, the normal force from the table increases and the wire can never lift off. Reason (R) is false: Parallel wires carrying currents in opposite directions repel, not attract. Furthermore, the magnetic forc
