Two large parallel conducting plates of net charge `2Q` and `-Q` are placed in a uniform external electric field `(Q)/(2Aepsilon_(0))` prependicular to plates as shown. The surface area of each plates is A. The charge on the left surface of the left plate and right surface of the right plate are respectively.

Options

A. `Q//2` ad `-3Q//2`
B. Q an 0
C. 0 and Q
D. `Q//2` and `Q//2`

Answer

C

Explanation

Making electrif field zero in left plate.

`(3Q-x)/(2A in_(0))-(-Q+x)/(2A in_(0))+(Q)/(2A in )=0`
`impliesx=2Q`
