Four similar (+q) are placed at origin O...

Four similar `(+q)` are placed at origin O, B, C and D as shown. The angles are as shown. Charges at B, C and D are equidistant from O at a distance of a. The forces of repulsion experienced by charge at O due to charges at B and D along CO are equal, given by `(q^(2)sqrt(3))/(8piepsilon_(0)a^(2))`. Find the relation between `theta_(1), theta_(2)` and `theta_(3)`:

A

`theta_(3)-theta_(2)=theta_(1)`

B

`2theta_(2)=theta_(1)+theta_(3)`

C

`theta_(3)=3(theta_(2)-theta_(1))`

D

None of these
