The additional charge transferred to the capacitors by the battery is 60 μC.
The increase in the total charge stored on the capacitors is 60 μC.
<u>Explanation</u>:
C = εоA / d
If the separation is halved, then the capacitance will be doubled and according to the equation q = CV, the charge will be doubled too.
- Initial charge of the capacitor is:
q = CV
= (6e - 6) (10)
= 60 μC
Final charge of the capacitor:
q = (2C)V
= (2 6e - 6)
(10)
= 120 μC
additional charge transmitted is:
q' = 120 - 60
= 60 μC
- initial total charge:
= (C1 + C2) V
= (6 + 6) (10)
= 120 μF
final total charge:
= (C1 + C2) V
= (2 6 + 6)
(10)
= 180 μF
Increase in the charge:
q' = 180 - 120
= 60 μC
