Open in App
Solution
The correct option is A zero
Since the outer plate of B is free, there cannot be any charge accumulation on it and the magnitude of the charge on the plates of a parallel plate capacitor is equal. So, there cannot be any charge on the capacitor B. Hence the correct choice is (a).
