Q 11 There are two thin parallel plates carrying equal and opposite
charge densities as shown If they are placed close to each other as
shown, then net electric field is zero in

(1) Only region I
(2) Only region II
(3) Only region Ill
(4) Both region I and region III

Dear student,

In the regions, I and III,
electric field E is zero This is because charge is not enclosed by
the respective plates

Electric field E in region
II is given by the relation,
