Q89NEET 2020 · PHASE 1Easy

Electric Potential & Equipotentials

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:

Show answer and solution

Answer: (d)

$E = -\frac{dV}{dr}$ ; if $V$ is constant everywhere in the region, its gradient is zero.
$E = 0$ (the volume value is not needed)
So the answer is (d) zero.
