1. The problem statement, all variables and given/known data

A point charge mass of 0.0788kg and q charge= +6.62 uc is supended by a thread between the vertical plates of a parallege capacitor. If the angle of delflectionis 23.7 degress and the seperation between the plates is d= 0.0242m, whats the potential energy?
2. Relevant equations
v=w/q


3. The attempt at a solution
not sure, where to begin but....
V= w/q
w=1/2cv sq
F= keqq/r
F= 8.99e9 (6.62e-6)/.0242 sq

I think you'll need to draw a picture here.

i have 2 parallel lines then the distance btw the lines is d= .0242, then a pendulum ball @ an angle

What's the length of the pendulum?
