In the givven circuit, charge `Q_2` on the `2muF` capacitor changes as C is varied from `1muF` to `3muF`. `Q_2` as a function of 'C' is given properly by: (figures are drawn schematically and are not to scale)

A

(a)

B

(b)

C

(c)

D

(d)

Text Solution

Verified by Experts

The correct Answer is:
D

From the figure, `Q_2=(2)/(2+1)Q=2/3Q`
`Q=E((Cxx3)/(C+3))`
`:.` `Q_2=2/3((3CE)/(C+3))=(2CE)/(C+3)`
Therefore graph d correctly dipicts.
