Homework Help: Fixed point charges.

  1. Jul 26, 2009 #1
    A fixed point charge of +2q is connected by strings to point charges of +q and +4q (see attached diagram), Find the tensions [tex]T_1[/tex] and [tex]T_2[/tex].

    For [tex]T_2[/tex], I start summing the forces on the +4q point charge.




    Is this the correct vector equation?

    That's the right idea. (But I would use T1 and T2 to represent the magnitude of the tension forces.)
