Two long and parallel wires are at a distance of 0.1 m 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

`5xx10^(-3)N//m`

B

`5xx10^(-5)N//m`

C

`2.5xx10^(-5)N//m`

D

`2.5xx10^(-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)xx2xx5xx5)/(0.1)=5xx10^(-5)N//m`
