Question

In a certain 0.5 cm³ of space, electric potential is found to be 7 V throughout. What is the electric field in this region?

Accepted Answer

📌 Answer:

Given:
• Electric potential V = 7 V = constant throughout the region.

Concept:
Electric field is related to potential by:

E = −dV/dr

Since V is constant, dV/dr = 0.

∴ E = 0 (Electric field is zero in this region)

Key Point: A uniform potential means no change in potential → no electric field.
