Two long and parallel wires are at a distance of `0.1m` and a current of `5 A` is flowing in each of these wires. The force per unit length due to these wires will be

A

`5 xx 10^(-3) N//m`

B

`5 xx 10^(-5) N//m`

C

`2.5 xx 10^(-5) N//m`

D

`2.5 xx 10^(-5) N//m`

Text Solution

Verified by Experts

The correct Answer is:
B
`(F)/(I) = (mu_(0))/(4pi) = (2i_(1)i_(2))/(d) = (10^(-7) xx 2 xx 5 xx 5)/(0.1) = 5 xx 10^(-5) N//m`
