What happens when a conducting sphere rubs against metal?

Click For Summary
SUMMARY

When a conducting sphere rubs against metal, the interaction does not result in a fixed charge on the conducting sphere. This is due to the nature of metals acting as reservoirs of electrons, allowing for the easy flow of electrons in and out. The discussion emphasizes that the charge on the conducting sphere remains variable rather than fixed, challenging the notion of permanent charging through friction.

PREREQUISITES
  • Understanding of basic electrostatics
  • Familiarity with the concept of electron flow in conductors
  • Knowledge of frictional charging principles
  • Basic physics concepts related to charge and conductivity
NEXT STEPS
  • Research the principles of electrostatic induction
  • Explore the effects of friction on different materials
  • Learn about the behavior of electrons in conductive materials
  • Investigate the concept of charge neutrality in conductors
USEFUL FOR

Students studying physics, educators teaching electrostatics, and anyone interested in the principles of charge transfer and conductivity in materials.

I know that metal is a "reservoir" of electrons, whereby electrons can flow out and in easily, so when conducting sphere is rubbed against metals, is there even a resulting charge on the conducting sphere?

I think there will not be a fixed charge on conducting material
