Question

Charges $Q_1$ and $Q_2$ are at points $A$ and $B$ of a right angle triangle $O A B$ (see figure). The resultant electric field at point $O$ is perpendicular to the hypotenuse, then $Q_1 / Q_2$ is proportional to

Select the correct option:

A

$\frac{x_1^3}{x_2^3}$

B

$\frac{x_2^2}{x_1^2}$

C

$\frac{x_1}{x_2}$

D

$\frac{x_2}{x_1}$
