Right Hand Rule Associated Question

AI Thread Summary
The discussion centers on the behavior of two current-carrying wires and whether they will attract or repel each other. The correct answer is that the wires will repel each other due to the direction of their currents. The confusion arises from the distinction between electric and magnetic fields, with the focus being on the magnetic fields generated by the currents. Participants are encouraged to apply the right-hand rule to determine the magnetic field of one wire and the force it exerts on the other. Understanding this principle clarifies why the wires repel rather than attract.

Homework Statement


What will happen to the two wires shown in the diagram (in the attachments)?

A: nothing will happen
B: repel each other
C: attract each other

The answer is "B", they will repel each other.

Homework Equations





The Attempt at a Solution


I thought it would attract because the current in the two wires are coming in from different directions/ sides signifying that the electric fields are not the same, and if the electric fields are different then there must be an attraction.

But that was just my guess, could someone tell me why the two wires repel each other instead of attract each other?

This is a question about magnetic fields, not electric fields.

Answer these:
(1) What is the magnetic field created by the bottom wire? (Use a right hand rule.)
(2) What force does that magnetic field exert on the top wire? (Use a right hand rule.)
 

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'

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...
