Two small spheres of mass m are suspended from strings of length L that are connected at a common point.(adsbygoogle = window.adsbygoogle || []).push({});

One sphere has charge Q, the other has 2Q.

The strings make angles (theta1) and (theta2) with the vertical.

(a) How are theta1 and theta2 related?

(b) Assume theta1 and theta2 are small. Show that the distance r between the spheres is

[tex]r \approx \frac {4k_eQ^2L}{mg} [/tex]

supposed to be a paren around the whole fraction... :uhh: the whole thing raised to 1/3 power

Thanks very much for answering :)
