Two infinitely long parallel conductors carrying currents I 1 and I 2 are at distance d apart. The force \(F\) on length \(L\) of one conductor due to the other is :
- A proportional to L but independent of \(I 1 \times I 2\)
- B proportional to \(I 1 \times I 2\) but independent of L
- C proportional to \(I1 \times I2 \times L\)
- D proportional to \(L / I1 \times I2\)
Answer & Solution
Correct Answer
(C) proportional to \(I1 \times I2 \times L\)
Step-by-step Solution
Detailed explanation
\(F = \frac{\mu_0 I_1 I_2 L}{2 \pi d}\) \(F \propto I_1 I_2 L\)
