Two 10 cm long, straight wires, each carrying a current of 5 A are kept parallel to each other. If each wire experienced a force of 10 - 5 N , then separation between the wires is _____ cm .

Correct answer

0

Step-by-step solution

Given: F = 10 - 5   N Force between wires F l = μ 0 i 1 i 2 2 π d , where, d is separation between them. ⇒ 10 - 5 0 . 1 = 2 × 10 - 7 × 25 d ⇒ d = 50 × 10 - 3   m = 5   cm
