Question

three identical capacitors of capacitance c are connected in series and then the first and the last conductors of the combination are connected to earth. a charge q is communicated to the second conductor of first capacitor. what will be the potential of this conductor ?

Answer 1

Answer:

Explanation:

The answer must be zero potential.

We know that the 3 capacitors are connected in series, hence the potential of the capacitors should be different but charge should be same. As same charge is going through the capacitors then the 3 will have equal charge distribution.

Since, the 1st and the last capacitors are connected to zero potential hence the net charge in the capacitors also becomes zero.
