Question

If current in both conductors is doubled, the force between them becomes
Options
A 2F
B 4F
Correct Answer
C 5F
D F/2
Correct Answer

Option B is the correct answer.

Detailed Explanation

Force per unit length between two parallel current-carrying wires: F is proportional to I1*I2. Doubling BOTH currents multiplies the force by 2x2 = 4, so the new force is 4F.

Hint

Force per unit length between two parallel current-carrying wires: F is proportional to I1*I2.
