two infinite wires, carrying currents i1...

two infinite wires, carrying currents `i_1 and i_2`., are lying along x-and y-axes, as shown in the x-y plane. Then,

A

locus of points where B is zero is a circle

B

locus of points where B is zero is a line

C

B decay heperbolically along any line parallel to x-axis

D

B decay heperbolically along any line parallel to y-axis

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Magnetic field may be zero in first and third quadrants.
`(mu_0I)/(2piy)=(mu_I_2)/(2pix)` represents a straight line passing through the
origin.
