Calculating Velocity for Horizontal Motion in a Uniform Magnetic Field

Click For Summary
SUMMARY

The discussion centers on calculating the velocity required for a negatively charged stone (0.010C) to maintain horizontal motion in a uniform magnetic field (1.70T) directed into the page. Participants concluded that due to the nature of magnetic forces acting perpendicular to the motion, achieving horizontal motion without vertical deviation is impossible under the given conditions. The question may be misleading, as it suggests a trick scenario where the magnetic field's orientation could be interpreted differently.

PREREQUISITES
  • Understanding of magnetic fields and forces
  • Knowledge of charged particle dynamics in magnetic fields
  • Familiarity with the right-hand rule for magnetic force direction
  • Basic physics concepts related to motion and forces
NEXT STEPS

Homework Statement


A stone with a negative net charge of 0.010C is given a constant horizontal motion in a uniform magnetic field in the direction pointing into the page. The field's strength is 1.70T. How fast does the stone have to move in order for it to remain moving horizontally, without any vertical deviation?


Homework Equations


N/A


The Attempt at a Solution


The stone travels perpendicular to the force, so I think regardless of velocity, there will be vertical deviation.

Yes, that seems right. :confused:

Maybe they intend you to lay the paper flat, so that the B field is pointing downwards?
 
The question's diagram shows the magnetic field pointing into page, so I suppose its a "trick" question. Nevertheless, thank you for your help. I spent a long time looking at this because its the last question on the list.
