1. Two pith balls each have a mass of 1 g. and equal charge. One pith ball is suspended by an insulating thread. The other is brought to 3 cm from the suspended ball. The suspended ball is now hanging with the thread forming an angle of 30 degrees with the vertical. The ball is in equlibrium with Fe, Fg, and Ft.
Calculate Fg, Fe, and the charge of the balls.
2. F=kFaFb/dsquared
3. I really have no idea how to start it. Is Fg just 9.8m? For the rest I don't know how to get the force.
