`X` and `Y` are large, parallel conducting plates close to each other. Each face has an area `A`. `X` is given a charge `Q`. `Y` is without any charge. Points `A,B` and `C` are as shown in the figure.

A

The magnitude of electric field at B is `(Q)/(2epsilon_(0)A)`

B

The magnitude of electric field at B is `(Q)/(epsilon_(0)A)`

C

The electric field at A, B and C are of the same magnitude

D

The electric field at A and C are of the same magnitude, but in opposite directions

Text Solution

Verified by Experts

The correct Answer is:
B
Below figure shows the final charge distribution on the surfaces of the metal plates.

Electric field at point A is given as
`E_(A)=(Q)/(2Aepsi_(0))` toward left
Electric field at point B is given as
`E_(B)=(Q)/(2Aepsi_(0))` toward right
Electric field at point C is given as
`E_(C)=(Q)/(2Aepsi_(0))` toward right
Hence, correct answer is option (2).
