Question

A parallel plate capacitor with air as the dielectric has capacitance C. A slab of dielectric constant K and having the same thickness as the separation between the plates is introduced so as to fill one-fourth of the capacitor as shown in the figure. The new capacitance will be

  1. open parentheses K plus 3 close parentheses fraction numerator C over denominator 4 end fraction    
  2. left parenthesis K plus 2 right parenthesis fraction numerator C over denominator 4 end fraction    
  3. left parenthesis K plus 1 right parenthesis fraction numerator C over denominator 4 end fraction    
  4. fraction numerator K C over denominator 4 end fraction    

The correct answer is: open parentheses K plus 3 close parentheses fraction numerator C over denominator 4 end fraction
