Coulomb's law and drawing vectors

AI Thread Summary
The discussion revolves around solving a problem involving three charges on the x-axis and determining the effect of charge A and charge C on charge B using Coulomb's law. Participants emphasize the importance of drawing a diagram to visualize the forces acting on charge B, noting that charge A is positive and charge B is negative, while charge C is also positive. The forces exerted by A and C on B are discussed, with hints provided about the direction of these forces based on the nature of the charges. There is a request for resources that offer step-by-step guidance on similar problems. Overall, the focus is on understanding how to apply Coulomb's law and vector representation in this context.

Homework Statement


Three charges are on the x~axis about five cm apart. Charge A is three micro C, charge B is negative four micro C, and charge C is five micro C. What is the effect on B?

Homework Equations


I have no idea how to solve this or the formula involved.


The Attempt at a Solution



Completely clueless, just would like to know how to solve it.

Coulomb's law. Draw the force vectors calculated for both F_{a->b} and F_{c->b}.

F_{e}=\frac{Kq_{1}q_{2}}{r^{2}}
 
sorry I'm lost, i have no idea how to implement that. what are force vectors?
 
Its ok. Did you draw a diagram? Start by drawing a diagram. I am assuming that A is on the left of B and B is on the left of C, right?

Does A exert a force to the left or the right on B?

How about C, does it exert a force to the left or the right on B?
 
Hint: think opposites attract.. Which of the charges are positively charged? Which are negatively charged?
 
how do you draw the diagram? I'm completely confused, you're talking to me in riddles. do you know of a website that shows step by step how to work these type of problems?

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 '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...
