Question

(39. In the given circuit the charge on lower plate B is

(1) Positive
(2) Negative
(3) Zero
(4) Infinite​

Answer 1

The charge on lower plate B is zero because no charge will pass through the plates( A and B ) of the conductors. Current will only pass through the resistors. So the answer will be (3).

Answer 2

Option 3 is the right answer.

Explanation:

The charge on the lower plate is zero columns because capacitor does not store any kind of charge. It store only the charges with opposite polarity.

It means if the charge on the one plate, take B, is +2 columns, then the charge on the plate A ( opposite plate) must have the charge of -2 coulomb.

The charges are only on the resistors.
