SUMMARY

The discussion centers on a physics problem involving charge transfer between a negatively charged plate (-3.0 µC) and a positively charged rod (+2.0 µC). To equalize their charges, the calculation shows that transferring 2.0 µC results in the need to move approximately 1.25 x 1019 electrons. A correction was noted regarding the charge-to-electron conversion factor, emphasizing the importance of accurate calculations in charge transfer problems.

PREREQUISITES
  • Understanding of electric charge and its units (microcoulombs, µC)
  • Knowledge of electron charge (-1.6 x 10-19 coulombs)
  • Basic algebra for solving equations
  • Familiarity with concepts of charge conservation
NEXT STEPS
  • Review the principles of charge conservation in electrostatics
  • Learn about the calculation of electron transfer in charge equalization
  • Explore the concept of Coulomb's Law and its applications
  • Study the effects of charge distribution on electric fields
USEFUL FOR

Students in introductory physics courses, educators teaching electrostatics, and anyone interested in understanding charge transfer and its calculations.

Basic Electricity Question. Needs Checking!??

Homework Statement



A plate carries a charge of -3.0 uC, while a rod carries a charge of +2.0 uC. How many electrons must be transferred from the plate to the rod, so that both objects have the same charge?


The Attempt at a Solution



-2.0 uC / -1.6 x 10^-10 = 1.25 x 10^19 electrons

The wording of this question kinda throws me off. appreciate the help!
 
Physics news on Phys.org
Your number of 2C is the correct charge, but there is an error in your charge/electron number. Otherwise you are doing it correctly.
 
Oh, and post moved from Advanced Physics to Intro Physics.
