Question

Two parallel sheets 1 and 2 carry uniform charge densities s subscript 1 end subscript and s subscript 2 end subscript, as shown in the figure. The magnitude of the resultant electric field in the region marked I is open parentheses s subscript 1 end subscript greater than s subscript 2 end subscript close parentheses.

  1. fraction numerator s subscript 1 end subscript over denominator 2 stack I with ˆ on top subscript 0 end subscript end fraction    
  2. fraction numerator s subscript 2 end subscript over denominator 2 stack I with ˆ on top subscript 0 end subscript end fraction    
  3. fraction numerator s subscript 1 end subscript plus s subscript 2 end subscript over denominator 2 stack I with ˆ on top subscript 0 end subscript end fraction    
  4. fraction numerator s subscript 1 end subscript minus s subscript 2 end subscript over denominator 2 stack I with ˆ on top subscript 0 end subscript end fraction    

The correct answer is: fraction numerator s subscript 1 end subscript plus s subscript 2 end subscript over denominator 2 stack I with ˆ on top subscript 0 end subscript end fraction
