Electrostatic Potential And Capacitance Ques 3
3. In a certain region of space with volume $0.2$ $m^{3}$, the electric potential is found to be $5$ $ V$ throughout. The magnitude of electric field in this region is :
[2020]
(a) $0.5$ $ N / C$
(b) $1$ $ N / C$
(c) $5$ $ N / C$
(d) zero
Show Answer
Answer:
Correct Answer: 3.(d)
Solution:
- (d) Since, electric potential is constant throughout the volume, hence electric field,
$E=-\frac{d V}{d r}=0$.
