A long straight wire is carrying current II in +z+z direction. The x−yx-y plane contains a closed circular loop carrying current I2I_2 and not encircling the straight wire. The force on the loop will beA long straight wire is carrying current I in +z direction. The x-y plane contains a closed circular loop carrying

Options

  1. Aμ0/1/0/2π\mu_0 /_1 /_0 / 2 \pi
  2. Bμ0I1I2/4π\mu_0 I_1 I_2 / 4 \pi
  3. Czero
  4. Ddepends on the distance of the centre of the loop from the wire

Correct answer

D. depends on the distance of the centre of the loop from the wire

Step-by-step solution

Situation is shown in the figure given below A long straight wire is carrying current I in +z direction. The x-y plane contains a closed circular loop carrying Thus, the force depends on the distance of the centre of the loop from the wire.
