Two long parallel wires are at a distance of 1 m. Both of them carry 1A of current. The force of attraction per unit length between the two wires is

A

`2xx10^(-7)N//m`

B

`4xx10^(-7)N//m`

C

`8xx10^(-7)N//m`

D

`10^(-7)N//m`

Text Solution

Verified by Experts

The correct Answer is:
A
`F=(mu_(0)i_(1)i_(2))/(2pid)=(4pixx10^(-7)xx1xx1)/(2pixx1)=2xx10^(-7) N//m`
