Three infinite current carrying conductors are placed as shown in figure. Two wires carry same current while current in third wire is unknown. The three wires do not intersect with each other and all of them are in the plane of paper. Which of the following is incorrect about a point ‘P’  which is also in the same plane :
  • a)
    If the current in the third wire is (right to left) then magnetic field will be zero at  P  for all value of  x.
  • b)
    Magnetic field intensity at P is zero for all values of  x. 
  • c)
    If the current in the third wire is  (left to right) then magnetic field will be zero at P  for all values of x. 
  • d)
    If the current in the third wire is  (right to left) then magnetic field will be zero at  P  for all value of x.
Correct answer is option 'A,B,C'. Can you explain this answer?
