Charging + Electristatic Flashcards
A neutral metal sphere is touched by a negatively charged metal rod. During the process, electrons are transferred from the ____ to the _____ and the sphere acquires a ____ charge.
Charged rod, neutral sphere, negative
A neutral metal sphere is touched by a positively charged metal rod. during the process, protons are transferred from the _____ to the _____ and the sphere acquires a _____ charge.
None of this occurs
A metal sphere is electrically neutral. It is touched by a positively charged metal rod. As a result, the metal sphere becomes charged positively. Which of the following occur during the process?
The metal sphere loses electrons
Electrons are transferred from the sphere to the rod
The overall charge of the system is conserved.
What is the difference between induction and conduction?
Induction is when you don’t touch the object, while with conduction you touch the object
If the object you’re holding is positive what kind of induction is happening?
Negative
