Question
The electric field above a uniformly charged nonconducting sheet is E. If the nonconducting sheet is now replaced by a conducting sheet, with the charge same as before, the new electric field at the same point is :
Options
A.2E
B.E
C.E/2
D.None of these
Solution
E = 
due to non-conducting sheet.
ᐃE′ =
due to conducting sheet, but σ1 = 
∴ Result is same i.e. E′ = E
due to non-conducting sheet. ᐃE′ =
due to conducting sheet, but σ1 = ∴ Result is same i.e. E′ = E
