In the given figure, electric field lines of forces between two parallel metallic plates are passing from a positive plate P to a negative plate Q.The intensity of the electric field is
Correct answer: D. Uniform between the plates
- A. Zero between the plates
- B. Stronger near the plate P
- C. Stronger near the plate Q
- D. Uniform between the plates
Explanation
The correct answer is that the intensity of the electric field is uniform between the plates. This is because the electric field lines between two parallel metallic plates create a uniform field, which means the electric field intensity is also uniform at each point. The field is not zero because there is a constant potential difference maintained between the plates. The other options are incorrect, as they suggest non-uniformity or zero field, which does not occur between parallel plates with a potential difference.

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
