Correct answer
C
Step-by-step explanation
When the capacitor is completely charged, the total energy in the circuit is with the capacitor and that energy is
When half energy is with the capacitor in the form of electric field between the plates of the capacitor we get where is the charge on plate of the capacitor
When half energy is with the capacitor in the form of electric field between the plates of the capacitor we get where is the charge on plate of the capacitor
