Question
A parallel plate capacitor contains a positively charged plate on the left, and a negatively charged plate on the right. A proton in between the plates is moving to the right. Which statement is true? Select one: The potential energy of the proton is decreasing and it is moving to a region having a lower potential. The potential energy of the proton is decreasing and it is moving to a region having a higher potential. The potential energy of the proton is increasing and it is moving to a region having a lower potential. The potential energy of the proton is increasing and it is moving to a region having a higher potential.Explanation / Answer
The potential is relatively more near the positive charge compared to negative charge. in the parallel plate capacitor, the positive charge will be at higher potential, and negative charge will be at lower potential. As the positive charge moving towards right (negative plate), the potential energy of the proton is negative that is decreases.
So, option (B) is correct answer.
