Question

A ring of radius R is uniformly charged, and it carries a total charge Q. At a point which is at a distance of $\frac{R}{\sqrt{3}}$ from the center and lying on the axis of the ring, electric field due to half part is $E_1$ & due to the other half part is $E_2$, then

• A. $\frac{E_1}{E_2}=\frac{\sqrt{3}}{1}$
• B. $\frac{E_1}{E_2}=\frac{1}{\sqrt{3}}$
• C. $\frac{E_1}{E_2}=\frac{2}{1}$
• D. $\frac{E_1}{E_2}=1$

Answer 1

The correct option is D $\frac{E_1}{E_2}=1$


Using concept of symmetry, we can say that,
$\left|\overrightarrow{E_1}\right|=\left|\overrightarrow{E_2}\right|$
$\therefore$ Option $d$ is correct.
