Question

Two long, straight, parallel wires are 5 cm apart and carry currents I₁ and I₂ in the same direction. If 2I1 = 3I₂ , then at a point P, 2 cm from wire 2,

(A) \(\vec{B_1}\) = \(\vec{B_2}\)

(B) \(\vec{B_1}\) = - \(\vec{B_2}\)

(C) \(\cfrac{B_1}{B_2}\) = \(\cfrac 94\)

(D) \(\cfrac{B_1}{B_2}\) = \(\cfrac 49\)

Answer 1

Correct option is (B) \(\vec{B_1}\) = - \(\vec{B_2}\)
