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.
[tex]F_{net,4q}=F_{q}+F_{2q}+T_2[/tex]
[tex]0=F_{q}+F_{2q}+T_{2}[/tex]
[tex]T_2=-(F_{q}+F_{2q})[/tex]
Is this the correct vector equation?
