A positive point charge is placed at P in front of an earthed metal sheet S.Q and R are two points between P and S as shown in the diagram. If the electric field strength at Q and r are respectively `E_(Q)` and `E_(R)`, which one of the following statement is`//`are false?

Options

A. `E_(R)=0`
B. `E_(Q)=E_(R)`
C. `E_(Q) gt E_(R)`
D. `E_(Q) lt E_(R)`

Answer

A, B, D

Explanation

By mothod of electrical images
Electric field `Q=vec(E)_(P)+vec(E)_(P). P`
