18 Questions
What is the purpose of rubbing two neutrally-charged objects together?
To transfer electrons from one object to another
What determines the direction of electron transfer when rubbing two neutrally-charged objects together?
The electron affinity of the objects
What is the purpose of the triboelectric series mentioned in the text?
To identify which materials have a higher chance to gain or lose electrons
Which method of charging allows the transfer of electrons without physical contact between two uncharged objects?
Charging by Induction
In charging by induction, how can two neutral metal spheres be charged with separate positive and negative charges?
By introducing a charged object into the system
What term describes the chance for a neutrally charged object to gain electrons?
Electron Affinity
What happens when a negatively-charged object is brought into contact with a neutral metal sphere?
Excess electrons move from the object onto the metal sphere.
If a positively charged object is brought into contact with a neutral metal sphere, what happens?
Electrons from the metal sphere move to the positively charged object.
What is the process of transferring electrons from one object to another through rubbing known as?
Charging by Friction
Why do protons not transfer between objects during the charging process?
Protons are tightly bound to their nucleus and cannot easily leave.
In charging by induction, what happens when a charged object is brought close to a neutral conductor?
Electrons move from the conductor to the charged object.
What is the result when a neutral metal sphere comes in contact with a positively charged object?
The metal sphere acquires a positive electrical charge.
According to Coulomb's Law, what happens to the electrostatic force as the separation distance between charges increases?
It decreases
If two charges are brought closer together, what happens to the interaction between them according to Coulomb's Law?
The interaction increases
What is the relationship between the amount of charge on objects and the electrostatic force according to Coulomb's Law?
They are directly proportional
In a system where two charges experience an attractive force, what can be inferred about their nature?
The charges have opposite signs
When two like charges experience a repulsive force, what conclusion can be drawn about their charges?
Both charges are positive
What does Charles-Augustin de Coulomb's mathematical equation describe?
Electric field between charges
Test your knowledge on the transfer of electric charges through rubbing objects together. Understand how electrons can be transferred between neutrally-charged objects by friction. Determine from which object the electrons will be transferred in a specific scenario.
