Question

In the circuit shown the capacitor of capacitance C is initially uncharged. Now the capacitor is connected in the circuit as shown. The charge passed through an imaginary circular loop parallel to the plates (also circular) and having the area equal to half of the area of the plates, in one time constant is:

  1. C epsilon open parentheses 1 minus fraction numerator 1 over denominator e end fraction close parentheses    
  2. fraction numerator C epsilon over denominator 2 end fraction open parentheses 1 minus fraction numerator 1 over denominator e end fraction close parentheses    
  3. fraction numerator C epsilon over denominator 4 end fraction    
  4. zero    

The correct answer is: zero


    In the given cross-section which lies inside the capacitor plates , no charge flows. hence the required charge is 0.
