Two long straight conductors with corrents `I_(1)` and `I_(2)` are placed along X and Y axes. The equation of locus of points of zero magnetic induction is :

A

`y = x`

B

`y = I_(2)/I_(1)x`

C

`y = I_(1)/I_(2)x`

D

`y = x/(I_(1).I_(2))`

Text Solution

Verified by Experts

The correct Answer is:
C

`B_(P) = 0`
`B_(1) - B_(2) = 0`
`rArr B_(1) = B_(2)`
`(mu_(0)I_(1))/(2xy) = mu_(0)/(2pi).I_(2)/x, therefore y = I_(1)/I_(2) x`
