I've been raking my brain for two hours!!!!!!!! Please help.

The two pith balls in Figure 20-15 each have a mass of 3.9 g and equal charge. One pith ball is suspended by an insulating thread. The other is brought to x = 3.1 cm from the suspended ball. The suspended ball is now hanging with the thread forming an angle of 30.0° with the vertical. The ball is in equilibrium with FE, Fg, and FT. Calculate each of the following.

Your question concludes with "Calculate each of the following" but there is nothing following....makes it kind of hard to calculate anything...maybe more information would help?
