Coulombs Law and Electric Charges

AI Thread Summary
A charge of 7.00 mC is positioned at each corner of a square with sides measuring 0.80 m, and the discussion revolves around calculating the force on each charge. The problem presents challenges in determining the net force, particularly for one of the charges. Participants suggest leveraging the symmetry of the square to simplify the calculations, noting that the forces acting on each charge are equivalent in direction and magnitude. Understanding the geometry, such as the properties of an equilateral triangle, is highlighted as beneficial for solving the problem. Overall, the conversation emphasizes the importance of symmetry in electric charge interactions.

Likewise, this similar problem also has me stumped
A charge of 7.00 mC is placed at each corner of a square 0.80 m on a side. Determine the magnitude of the force on each charge.

Any help would be greatly appreciated!

Do you know what an equilateral triangle is?

Daniel.
 
I'm insulted.

Yes, I know what an equilateral triangle is. It has three sides of equal length, and all three angles are 60 degrees. As I stated, I found the net force on two of the points, but Q(1) is giving me issues. Obviously the way I'm trying is wrong, so I'd like help, thank you.
 
You deleted the problem.Anyway,since you know what a equilateral triangle is,u might use the fact that the problem is symmetric (actually the geometry) so the directions of the forces are equivalent.If the charges were all 3 equal,then the problem would b solved if u managed to find the net foce acting only on one angle,since on the other two is practically the same,in modulus,of course.

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
