Question

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

(1) 5 N/C 

(2) Zero 

(3) 0.5 N/C 

(4) 1 N/C

Answer 1

Correct answer is (2) Zero

Potential is constant throughout the volume 

∴ Electric field is zero.
