Question

Three straight, parallel wires are coplanar and perpendicular to the plane of the page. The currents I₁ and I₃ are directed out of the page. If wire 3 experiences no force due to the currents I₁ and I₂, then the current in the wire 2 is:

Options

• I₂ = 2 I₁ and directed into the page

• I₂ = 0.5 I₁ and directed into the page

• I₂ = 2 I₁ and directed out of the page

• I₂ = 0.5 I₁ and directed out of the page

Answer 1

I₂ = 2 I₁ and directed out of the page
