      Question

      Two long parallel wires 2 cm apart carry 5 A and 3 A

      currents in the same direction. What is the force per unit length on one wire?
      A 1.5 × 10⁻⁴ N/m Correct Answer Incorrect Answer
      B 2.25 × 10⁻⁴ N/m Correct Answer Incorrect Answer
      C 3 × 10⁻⁴ N/m Correct Answer Incorrect Answer
      D 4.5 × 10⁻⁴ N/m Correct Answer Incorrect Answer

      Solution

      Given:

      • Distance between wires: d = 2 cm = 0.02 m
      • Current in wire 1: I₁ = 5 A
      • Current in wire 2: I₂ = 3 A
      • Currents are in the same direction
      Formula for force per unit length between parallel wires: The force per unit length between two parallel current-carrying wires is:
