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