Question

In the circuit shown in the figure, switches S1 and S2 have been closed for a long time

  1. Charge on the capacitor is 100 muC.    
  2. Charge on the capacitor is 20 muC    
  3. Charge on the capacitor increases to 120 muC if one third of the gap of the capacitor’s plates is filled with a dielectric (K = 2) of same area    
  4. Charge on the capacitor remains unchanged if one third of the gap of the capacitor’s plates is filled with a dielectric (K = 2) of same area.    

The correct answer is: Charge on the capacitor is 100 muC.
