Two parallel conductors carry current in opposite directions as shown ...

The magnetic field at C due to first conductor is

(since, point C is separated by

from 1st conductor). The direction of field is perpendicular to the plane of paper and directed outwards.
The magnetic field at C due to second conductor is

(since, point C is separated by d/2 from 2nd conductor)
The direction of field is perpendicular to the plane of paper and directed inwards.
Since, direction of B₁ and B₂ at point C is in opposite direction and the magnetic field at C is zero, therefore,
B₁ = B₂

On solving I = 30.0 A

Two parallel wires in the plane of the paper are distance X0 apart. A point charge is moving with speed ubetween the wires in the same plane at a distance X1 from one of the wires. When the wires carry current ofmagnitude I in the same direction, the radius of curvature of the path of the point charge is R1. In contrast,if the currents I in the two wires have directions opposite to each other, the radius of curvature of the path is R2. id X0/X1=3 the value of R1/ R2 is Correct answer is '3'.
