Question

100. Two long wires carring current i and 2i are placed along co-ordinate axes x and y respectively.
The locus of point where magnetic field is zero is
2y-x=0
(2)
2x-y=0
(3)
y-x=0
y=0​

Answer 1

Answer:

Explanation:

B1=μ0i2πy,⊙

B2=μ0.2i2πx,⊗  

B1=B2

μ0i2πy=μ0.2i2πx

x=2y⇒2y−x=0

Answer 2

Answer:

2ycx=0... ......
