How can I plot the electric field vs position for two charges?

AI Thread Summary
To plot the electric field versus position for two charges, one must understand that the electric field (E) is defined as the force per unit charge. A positive electric field indicates a direction towards positive x for positive charges. The discussion highlights confusion regarding the correct approach to plotting this relationship, emphasizing the need for proper equations. Detailed explanations and formulas are requested to clarify the plotting process. Understanding the principles of superposition for electric fields from multiple charges is crucial for accurate representation.

A positive E usually means an electric field that goes to the right, or a force towards positive x on positive charges.

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...
