How Does a Charged Bullet Respond to Earth's Magnetic Field?

Click For Summary
SUMMARY

The discussion focuses on two physics problems involving the interaction of charged particles with magnetic fields and electrical resistance in powerlines. The first problem calculates the deflection of a charged bullet, weighing 3.80 grams and traveling at 180 m/s, in a magnetic field of 5.00 x 10-5 T after traveling 1.00 km. The second problem addresses the resistive power loss in a high-voltage powerline operating at 500,000 V-rms with a current of 500 A and a resistance of 0.05 Ω/km over 200 km. Key equations for these scenarios include the Lorentz force equation and the power loss formula.

PREREQUISITES
  • Understanding of Lorentz force and its application to charged particles
  • Familiarity with the concept of resistive power loss in electrical circuits
  • Knowledge of basic physics equations related to motion and electromagnetism
  • Ability to perform unit conversions and calculations involving distance and resistance
NEXT STEPS
  • Study the Lorentz force equation and its implications for charged particles in magnetic fields
  • Learn about resistive power loss calculations in electrical engineering
  • Explore the principles of electromagnetism as they relate to moving charges
  • Review the equations of motion for particles in external fields
USEFUL FOR

Physics students, electrical engineers, and anyone interested in the effects of magnetic fields on charged particles and the efficiency of power transmission systems.

I have a packet of physics questions and there were to that I just couldn't solve, could anyone help me out with them please?

1. A 3.80-g bullet moves with a speed of 180m/s perpendicular to the Earth's magnetic flied of 5.00 X 10-5T. If the bullet possesses a net charge of 8.10X 10-9 C, by what distance will it be delfected from it's path due to it's magnetic field after it has traveled 1.00km

2. A high-voltage powerline operates at 500 000 V-rms and carries an rms current of 500 A. IF the resistance of the cable is 0.05Ω/km, what is the resistive power loss in 200km of the powerline?
