It is given that conducting plates have surface charge densities +σ and –σ. Since the sheet is large, the electric field E at energy point near the sheet will be perpendicular to the sheet.
The resultant electric field is given by:
E' = E + E = 2E
If σ is surface charge density, then
Electric field,
Hence, E' = 2E = V/m

Explanation:
- Gaussian surface:
- Consider a Gaussian surface between the plates and apply Gauss's law to find the electric field.
- Electric field:
- The electric field due to the positive plate is E1 = σ / (2ɛ0) away from the plate.
- The electric field due to the negative plate is E2 = -σ / (2ɛ0) towards the plate.
- The net electric field inside the plates is the sum of these two fields, E = E1 + E2 = σ / ɛ0.
- Direction of the electric field:
- The electric field points from the positive plate towards the negative plate.
- Conclusion:
- Therefore, the electric field in the region between the plates is σ / ɛ0 V/m. Option 'c' is the correct answer.
