Question

In a region of constant potential.

• A. The electric field is potential
• B. The electric field is zero.
• C. There can be no charge inside the region.
• D. Both (2) and (3) are correct

Answer 1

Answer: (D)

Both (2) and (3) are correct

Answer 2

: 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
