OH! Gravity and the tension in the strings!

Sure, so I have the magnitude. And each charge is sitting in a triangle with sides 20cm. So, if we put the first point at say, what I'll make my origin, then I have another point 20 cm to the right, so now its coordinates are (20,0) and the third charge would be at about... (10, 17.3)? Okay...

Well on each charge, since they are positioned in an equilateral triangle, they all have 2 forces acting on them, both at 30 degrees (I think?) and one would be at +30 degrees and one would be at -30 degrees. It was supposed to be kq^2, from the F=(k*q1*q2)/r^2 equation, but since q1=q2 we...

Hello there! I am a first year engineering student! I just started my second semester, and I've started electrical and magnetic physics for the first time :) Hope to talk to lots of you.

Homework Statement [/B] Three 3.0 g balls are tied to 80-cm-long threads and hung from a single fixed point. Each of the balls is given the same charge q. At equilibrium, the three balls form an equilateral triangle in a horizontal plane with 20 cm sides. Homework Equations F=kq1q2/r^2 F (of...
