Question

Figure shows the cross-sectional view of the hollow cylindrical conductor with inner radius ‘R’ and outer radius ‘2R’. Cylinder is carrying uniformly distributed current along it’s axis. The magnetic induction at point ‘P’ at a distance fraction numerator 3 R over denominator 2 end fraction from the axis of the cylinder will be

  1. Zero    
  2. fraction numerator 5 mu subscript 0 end subscript i over denominator 72 pi R end fraction    
  3. fraction numerator 7 mu subscript 0 end subscript i over denominator 18 pi R end fraction    
  4. fraction numerator 5 mu subscript 0 end subscript i over denominator 36 pi R end fraction    

The correct answer is: fraction numerator 5 mu subscript 0 end subscript i over denominator 36 pi R end fraction
