I would not be able to write the whole solution, because I am NOT GOOD IN lateX, and without that u would not be able to get the solution, but I can give u the basic trick required to crack it. Now, we know that the weight of ball is perpendicular to the earth and makes some angle with the thread(could be found using trigonometric ratios), so now take the components of the weight :- 1) along the thread and 2) perpendicular to the thread. Now whatever the component along the thread is, it would ultimately be balanced by the tension in the thread, and the horizontal component (component perpendicular to the thread) would be balanced by the electrostatic force of attraction. Now plug in the values and you will get the answer.

Can you elaborate it a little more further.Can you give the final equation.
