Question
The two plates are a distance D apart. The surface area of the face of each plate is A, the total charge on each plate is +Q and -Q, and the resulting uniform charge density is +sigma_0 and -sigma_0 respectively so that sigma_0=Q/A. Use the principle of superposition to identify the correct statement(s) about the electric field at points 1, 2, 3, and 4. The field at points 1 and 4 will be zero because the fields from positively and negatively plates will cancel each other The charge on negatively charged plate will not contribute to the field at point 4 because there's metal between them The field at points 2 and 3 will be the same and the magnitude of the field is twice that of the field from a single plate The charge on positively charged plate will not contribute to the field at point 1 because there's metal between them The fields at points 1 and 4 will be the same magnitude as from a single plate but in opposite directions The field at points 2 and 3 will be zero because the fields from negatively and positively charged plates cancel each otherExplanation / Answer
Electric field at 1 and 4 will be 0 since the electric fields at these two points are equal and opposite.
electric field at 2 ad 3 will add up being in same direction and is twice that is produced by a single plate
