In how many distinct named ways can an object be given an electric charge?
AFour ways, adding polarization as a fourth method
BOne way, by contact alone every single time
CThree ways, by contact, conduction, and induction
DTwo ways, by contact and induction only
Answer & Solution
Correct answer: C. Three ways, by contact, conduction, and induction
1. Three named methods for charging an object are given here.
2. These are charging by contact, by conduction, and by induction.
3. Polarization is a separation of charge inside a neutral object, not a fourth charging method in this list, so option A overcounts.
