Potential and field at two electric plates
AI Thread Summary
The discussion centers on the electric potential and field between two plates, confirming that work is required to move a positive test charge against the electric field from one plate to another. The equation V=kq/r is deemed irrelevant to the question, as it pertains to absolute potential rather than the specific scenario discussed. It is noted that the potential at the midpoint between the positive and negative plates is zero. The participants agree that the other answers provided are incorrect. Overall, the conversation emphasizes the relationship between electric potential, work, and the behavior of charges in an electric field.
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
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...
The answer to this question is statements (ii) and (iv) are correct.
(i) This is FALSE because the speed of water in the tap is greater than speed at the water surface
(ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not?
(iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
