In a region of constant potential

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

Tardigrade Admin · Accepted Answer

In a region of constant potential E=-(dV/dr) =0 (∵ V= constant) i.e. electric field is zero, so there can be no charge inside the region

Q. In a region of constant potential

the electric field is uniform

the electric field is zero

there can be no charge inside the region

both $(b)$ and $(c)$ are correct

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