Two long parallel wires carrying equal c...

Two long parallel wires carrying equal current separated by `1m`, exert a force of `2xx10^(-7)`N//m on one another. The current flowing through them is

A

`2.0A`

B

`2.0xx10^(-7)A`

C

`1.0A`

D

`1.0xx10^(-7)A`

Text Solution

Verified by Experts

The correct Answer is:
C
`(F)/(l)=(mu_(0))/(4pi)xx(2i_(1)i_(2))/(a)=(mu_(0))/(4pi)(2i^(2))/(a) ( :' i_(1)=i_(2)=i)`
`implies 2xx10^(-7)=10^(-7)xx(2i^(2))/(1) implies i=1A`
