Electric Potential Energy of a Charged Particle in an Electric Field

AI Thread Summary
When a charged particle is released in an electric field, its electric potential energy decreases as it moves to a region of lower potential. This energy is converted into kinetic energy, causing the particle to accelerate. The correct answer to the multiple-choice question is "b," indicating that the potential energy changes into kinetic energy. The analogy to a mass object in a gravitational field illustrates this concept effectively. Thus, the potential energy of the charged particle transforms into kinetic energy upon release.

Homework Statement


what will happen to the electric potential energy of a charged particle in an electric field when the particle is released and free to move?


2. multiple choice
a. it will increase
b. it will change into kinetic energy
c. it will remain unchanged



The Attempt at a Solution



i think its "b"
 
Physics news on Phys.org
A charged particle in an electric field is like a mass object under the influence of the gravitational field. Once the particle is let go, it will move to lower potential, and its potential energy will be converted into kinetic energy as the particle accelerates.
 
so i was correct?

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
