    Zero Potential In Uniform Electric Field

    Thank you very much! Just out of curiosity, how would one calculate the electrical energy between the plane and the sphere? There is a formula for the potential energy, U = [(Ke) * q1 * q2] / r but this seems to be only for point charges. How would you do this for a plane of charges...

    Zero Potential In Uniform Electric Field

    Hi, I actually have two questions... When dealing with a uniform electric field, where do we normally chose to 0V to be? Also, if we have a charged plate, we can treat it as a charged plane to use Gauss' Law right? Now, if we figure out the magnitude of the field created by that plane...

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    I'm sorry, but this is really bugging me. So if all this is true, that means that if I hung a charged sphere from the ceiling and took a metal plate and put sufficient charge on it, and pointed it at the sphere it would move to a point where is was hanging with a certain angle to the...

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    Yes, I went back a bit in the book and found it. The fact the the magnitude of the field does depend on the distance from the plane of charges didn't really mean much before I started electric potential. Now that I think about it, it seems really shocking. The field from this charged plate...

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    Ok thanks, Just to make sure I understand: _______________ Top plate ----------------- "Plane level" 1 ----------------- "Plane level" 2 _______________ Bottom plate By constant, do we mean that at Plane Level 1 and Plane Level 2, the magnitude of the field is the same? Or...

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    If the field is uniform between the two plates, wouldn't the voltage at different points be the same everywhere?

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    Thanks, that makes much more sense. One question though, is it actually possible to create a field that is constant everywhere in magnitude? Thanks, Dale.

    Voltage in Electric Field: What Happens When One Point is Chosen as Infinity?

    Hi, I seem to have trouble understanding this. The way I understand it leads to an inconsistency, so there must be something I'm not getting. Please forgive me if my explanation is unclear. The potential difference between two points (say A and B) in an electric field is: -[integral...

    Force pushing against piston in car engine

    Hi, Thanks a lot everyone. The reason I was asking is just to have a ball park number for the force required to push the piston. I would use this number to compare other methods of creating that same amount of force. Thanks alot, Dale

    Force pushing against piston in car engine

    Hi, I've done a bit of research to find my answer, but I haven't been able to come up with anything. Does anyone know what the average amount of force pushing against the piston in a car engine when the explosion occurs? I know it probably differs greatly with the car, but if anyone knows...
