I'm working on the following problem: A small spherical insulator of mass 9.00 x 10-2 kg and charge q1 = +0.400 µC is hung by a thin wire of negligible mass. A charge q2 = -0.700 µC is held 0.150 m away from the sphere and directly to the right of it, so the wire makes an angle with the vertical (see the drawing). http://www.boomspeed.com/boogiel80/hmwk18colulumb.gif [Broken] (a) Find the angle b) Find the tension in the wire. I figured out that the force that pulls between the two masses is around 1.12 x 10-1N. But after that I'm not sure where to go. I don't see how I can solve this problem using vecotor components (that is what I'm assuming I have to do). Also what does mass have to do with this problem? Does it have something to do with the tension? I normally can at least start problems, but this one I'm a little lost on.
