Question

For a set of oppositely charged infinite parallel plates what is true about the electric field inside and outside the plate?​

Answer 1

Answer:

The electric field outside the plates of two oppositely charged plane sheet of charge density σ is ZERO . Hence E due to oppositely charged infinite plates = σ/ε0 , At any points ,so it must be zero for all outside points

Answer 2

Answer:

The electric field is a non-zero constant within the plates and zero outside.

Explanation:

For a set of oppositely charged infinite parallel plates the electric field will be zero outside because we have oppositely charged plates that means electric fields move from positive to negative plate,so that's why approximately all electric fields lie between plates
