Net Force on Center Charge of Four Point Charges

AI Thread Summary
The discussion revolves around calculating the x-component of the net force on a central charge placed at the origin of a square formed by four other charges at its corners. The charges are defined as Aq, Bq, Cq, Dq, and Eq, with specified values and positions. Participants have applied Coulomb's law to determine the forces exerted by each charge and attempted to sum these forces, factoring in the angle of 45 degrees. They consistently arrive at a force value of 0.1249 N but are uncertain about the accuracy of their calculations. The conversation seeks clarification on whether their approach is correct or if any steps are overlooked.

Homework Statement



Four charges Aq,Bq,Cq, and Dq (q = 2.50 x 10-07C) sit in a plane at the corners of a square whose sides have length d = 69.5 cm, as shown in the diagram below. A charge, Eq, is placed at the origin at the center of the square.

DATA: A = 2, B = 8, C = 5, D = 4, E = -4. Consider the charge at the center of the square. What is the x-component of the net force on this charge?

Homework Equations



How do we set this up?

The Attempt at a Solution


We have found the charges of each of the electrons using Columns law, and then added the forces of each up and then multiplied it by cos(45deg). Each time we get .1249 N.

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...
