In a certain region of space with volume 0.2m30.2{m}^{3}, the electric potential is found to be 5V5V throughout. The magnitude of electric field in this region is:

Options

  1. A0.5NC−10.5N{C}^{- 1}
  2. B1NC−11N{C}^{- 1}
  3. C5NC−15N{C}^{- 1}
  4. Dzero

Correct answer

D. zero

Step-by-step solution

We know that electric field and potential are related as

E=−dVdxE = - \dfrac{dV}{dx}

Potential is constant throughout the volume
∴∴ Electric field is zero.
