I have used for gamma = 60 and got correct result but how do you know that gamma = 60 ?
I don't know why I thought that any of the angles is 90 degrees.
The correct result:
I mean all the forces working on the thread combined. A sum of all the forces working on that thread.
Which are only force of gravity and electrical force. And the sum of all those forces working on a thread should be 0.
I have provided all the information from the book. I have translated the...

They are both charged with the same charge as I already specified.
No information about if they are the same weight. Assume they are both the same weight.
Which thread tension you wish to found.
The combine force in the thread.
