Question

In a region of constant potential

• A. the electric field is uniform
• B. the electric field is zero
• C. there can be no charge inside the region
• D. both $(b)$ and $(c)$ are correct

Answer 1

Answer: (D)

In a region of constant potential
$E=-\frac{dV}{dr} =0$ ($\because V=$ constant)
i.e. electric field is zero, so there can be no charge inside the region
