Two very long, straight wires carrying, ...

Two very long, straight wires carrying, currents as shown in Fig. Find all locations where the net magnetic field is zero.

A

`y=sqrt2x`

B

`y=x`

C

`y=-x`

D

`y=-(x/2)`

Text Solution

Verified by Experts

The correct Answer is:
C
(c) Along th edashed line, `vecB_1 and vecB_2` are in opposite directions.
If the line has slope -1.00, then `r_1=r_2` and `B_1=B_2`. So `B_("tot")=0`
