Electric Potential at Point D in a Rectangle with Three Charges

AI Thread Summary
To find the electric potential at point D in the rectangle with charges A, B, and C, the individual potentials from each charge need to be calculated and then summed. The formula used is VEL = (k)(q1)/d, where k is the electrostatic constant, q1 is the charge, and d is the distance from the charge to point D. The discussion emphasizes the importance of adding the contributions from each charge to determine the total potential at point D. Participants express gratitude for clarification on the method. The solution involves straightforward application of the formula to each charge.

Homework Statement


The diagram shows three charges, A (+5.0 μC),B (-7.0 μC), and C (+2.0 μC), placed at three corners of a rectangle. Point D is the fourth corner. What is the electric potential at point D?

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 'Correct statement about a reservoir with an outlet pipe'

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...
