Two very large thin conducting plates having same cross sectional area are placed as shown in figure. They are carrying chaerges `Q` and `3Q`, respectivley. The variation of electric field as as function at x(for `x=0` to `x=3d`) will be best represented as by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Using the formula for electric field produced by large sheet `E=(Q)/(2A epsilon_(0))`
We get, `E_(A)=(4Q)/(2A epsilon_(0))`
`E_(B)=(2Q)/(2A epsilon_(0))(-hati)`, E_(C)=(4Q)/(2Aepsilon_(0))(+hati)`
