What is the direction of the resulting force on this current

AI Thread Summary
The discussion centers on determining the direction of the force on a vertical wire carrying an upward current in a magnetic field pointing north. Using the right-hand rule (RHR), participants analyze the orientation of their fingers, palm, and thumb to find the resulting force direction. The force is indicated to be directed to the left (west) when aligning the components correctly. Some users express difficulty in applying the RHR accurately. The conversation emphasizes the importance of understanding magnetic forces in relation to current direction and magnetic field orientation.

Homework Statement


A vertical wire carries a current straight up in a region where the magnetic field vector points due north. What is the direction of the resulting force on this current?

The diagram shows a force arrow perpendicular to the B (magnetic field arrow). The magnetic field is pointing out of the page.

Homework Equations



RHR
Fingers - pt I
Palm - magnetic field
Thumb- direction of force

The Attempt at a Solution


When I place my thumb in the direction of the arrow marked "F", it goes to the left (west) but I am having trouble lining every component of the RHR up.

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'

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...
