  • a)
    ir B0
  • b)
    2π ir B0
  • c)
    zero
  • d)
    π ir B0
Correct answer is option 'C'. Can you explain this answer?

A conducting circular loop of radius r carries a constant current i. I...
The magnetic field is perpendicular to the plane of the paper. Let us consider two diametrically opposite elements. By Fleming's Left hand rule on element AB the direction of force  will be Leftwards and the magnitude will be
dF = Idl B sin 90° = IdlB

On element CD, the direction of force will be towards right on the plane of the papper and the magnitude will be dF = IdlB.
