For the circuit shown in figure, which of the following statements is true ?

Options

A. With `S_(1)` closed `V_(1) = 15 V,V_(2) = 20 V`
B. With `S_(3)` closed `V_(1) = V_(2) = 25 V`
C. With `S_(1)` and `S_(2)` closed `V_(1) =V_(2) = 0`
D. With `S_(3)` closed `V_(1) = 30 V,V_(2) = 20 V`

Answer

D

Explanation

When `S_(3)` is closed, both capacitors attain common potential which is average of the two.
