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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
