Question

Force per metre on two wires carrying a current of 1 A placed 1 m apart is equal to:
Options
A 2.67 x 10-7 N
B 9.0 x 10-6 N
C 2.0 x 10-7 N
Correct Answer
D = 2x10-7 N/m. Historic ampere definition.
Correct Answer

Option C is the correct answer.

Detailed Explanation

F/L = mu0 I1I2/(2pid) = 2x10-7 N/m. Historic ampere definition.

Hint

F/L = mu0 I1I2/(2*pi*d) = 2x10-7 N/m.
