Question

In a certain region of space with volume 0.2 m³ , the electric potential is found to be 5V throughout. The magnitude of electric field in this region is: ____________.

Options

• 0.5 N/C

• 1 N/C

• 5 N/C

• zero

Answer 1

In a certain region of space with volume 0.2 m³ , the electric potential is found to be 5V throughout. The magnitude of electric field in this region is: zero.

Explanation:

We know,

E = `(-dV)/(dr)`

Since, potential is constant tluoughout, dV = 0, for any displacement dr.

Hence, electric field in this region is zero.
