**1. Homework Statement**

A small electrically charged object is suspended by a thread between the vertical plates of a parallel-plate capacitor. The acceleration of gravity is 9.8 m/s^2.

What is the potential difference between the plates? Answer in units of kV.

Given: tetha = 14 degrees

mass of the object = 152 mg

q = 15 nC

distance between the two plates = 5.6 cm

**2. Homework Equations**

I used the following:

delta V = U/Q

U = F x d

**3. The Attempt at a Solution**

I got U = 0.0000834176 Joules

and I got V = 5561.1733333 V

which is V = 5.561173333 kV

but it's wrong.

could someone please please tell me how to do it?
