Figure shows an arrangement of four identical rectangular plates A,B,C, and D each of area S. Find the charges appearing on each face (from left to right) of the plates. Ignore the separation between the plates in comparison to the plate dimensions.

A

Potential difference between the plates A and B is independent of `Q_1`.

B

Potential difference between plates C and D is independent of `Q_1`

C

Potential difference between the plates A and B is independent of `Q_2`.

D

Potential difference between plates C and D is independent of `Q_2`

Text Solution

Verified by Experts

The correct Answer is:
A, B
a.,b.
`xa+xb+(Q_(2)+x)c=0`
`x=(-Q_(2)c)/(a+b+c)`
`Q_(1)=y+x+y-Q_(2)-x`
`y=(Q_(1)+Q_(2))/(2)`
`V=(Q_(2)ca)/((a+B+c)Sepsilon_(0))`
