(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A small object of massmcarries chargeqand is suspended by a thread between the vertical plates of a capacitor. The plate separation isd. If the thread makes an angle [tex]\theta[/tex] with the vertical, what is the potential difference between the plates.

2. Relevant equations

[tex]\Delta V=-Ed[/tex]

[tex]C\Delta V=q[/tex]

E = kq/r^2

C = e0*A/d

3. The attempt at a solution

I drew a free body diagram, but since the length of the thread isn't given, it doesn't appear to help.

I'm having a hard time finding a relationship between theta, m, d, and q. Any hints?
