Question

The maximum field intensity on the axis of a uniformly charged ring of charge q and radius R  will be

  1. fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction times fraction numerator q over denominator 3 square root of 3 R squared end root end fraction
  2. fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction times fraction numerator 2 q over denominator 3 R squared end fraction
  3. fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction times fraction numerator 2 q over denominator 3 square root of 3 R squared end root end fraction
  4. fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction times fraction numerator 3 q over denominator 3 square root of 3 R squared end root end fraction

The correct answer is: fraction numerator 1 over denominator 4 pi epsilon subscript 0 end fraction times fraction numerator 2 q over denominator 3 square root of 3 R squared end root end fraction
