Q56 / 75 · JEE Main 2025 (4 Apr Shift 2) · Physics

A metallic ring is uniformly charged as shown in figure. AC and BD are two mutually perpendicular diameters. Electric field due to $\operatorname{arc} \mathrm{AB}$ to ' O ' is ' E ' is magnitude. What would be the magnitude of electric field at ' O ' due to arc ABC ?

A
2 E
Correct answer
B
$\sqrt{2} \mathrm{E}$
C
$\mathrm{E} / 2$
D
Zero

Hence, the correct answer is option: 'B'.
