Electric Charges and Fields - Result Question 29
29. From a point charge, there is a fixed point A. At $A$, there is an electric field of $500 V / m$ and potential difference of $3000 V$. Distance between point charge and $A$ will be
(a) $6 m$
(b) $12 m$
(c) $16 m$
(d) $24 m$

Answer:
Correct Answer: 29. (a)
Solution:
- (a) Given : Electric field (E) $=500 V / m$ and potential difference $(V)=3000 V$.
We know that electric field
(E) $=500=\frac{V}{d}$ or $d=\frac{3000}{500}=6 m$
[where $d=$ Distance between point charge and $A]$
