Question

In the given figure, a hollow spherical capacitor is shown. The electric field will not be zero at

  1. r less than r subscript 1 end subscript    
  2. r subscript 1 end subscript less than r subscript 2 end subscript    
  3. r less than r subscript 2 end subscript    
  4. r subscript 1 end subscript less than r less than r subscript 2 end subscript    

The correct answer is: r subscript 1 end subscript less than r less than r subscript 2 end subscript


    The electric field of a hollow spherical capacitor is localised in between inner and outer surface of the spherical conductor.
    Therefore, at point r subscript 1 end subscript less than r less than r subscript 2 end subscript, the electric field will not be zero.
