Calculating Potential Energy in a Parallel Plate Capacitor

In summary, a point charge with a mass of 0.0788kg and a charge of +6.62 uc is suspended between the vertical plates of a parallel capacitor with a separation of 0.0242m. The potential energy can be calculated with the equation v=w/q, where w=1/2cv^2 and F= keqq/r. However, the length of the pendulum is not given and cannot be determined with the given information.

Homework Statement



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 separation between the plates is d= 0.0242m, what's the potential energy?

Homework Equations


v=w/q


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

there isn't it only tells u the angle and the distances btw the 2 parallel lines
 

1. What is potential energy?

Potential energy is the stored energy an object possesses due to its position or state.

2. What is a potential energy problem?

A potential energy problem is a type of physics problem that involves calculating the potential energy of an object or system.

3. How do you calculate potential energy?

Potential energy can be calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height of the object.

4. What are some examples of potential energy problems?

Some examples of potential energy problems include calculating the potential energy of a ball at the top of a hill, a pendulum at its highest point, or a roller coaster at the top of a loop.

5. What are the different types of potential energy?

The two main types of potential energy are gravitational potential energy, which is associated with an object's position in a gravitational field, and elastic potential energy, which is associated with the deformation of an elastic object.
