Four long, parallel conductors carry equal currents of `5.0`. The direction of the currents is into the pge at points. `A` and `B` and out of the page at `C` and `D`. Calculate the magnitude and directionof the mgnetic field at point `P`, located at the centre of the square.

Options

A. W and Y X and Z
B. X and Z W and Y
C. W and Z X and Y
D. W and X Y and Z

Answer

D

Explanation

(d) To get magentic field in resultant direction, current in X
should be in and that in Z should be out, I in W should be in
and that in Y should be out.
