|
When two objects are rubbed together, there is a transfer of electrons. How do you determine which object acquires the transferred electrons?
|
|
Always transfer from the bigger to the smaller object, to make it even
|
|
|
Transfer is based on the initial charge of the two objects
|
|
|
Transfer is based on how much electron affinity that each object has
|
|
|
Always transfer from the more negative to the more positive object
|
Explanation:
Detailed explanation-1: -Solution: When two objects are rubbed, there is transfer of electrons from one object to another. The body which has excess electrons is negatively charged and the body which has deficit electrons is positively charged.
Detailed explanation-2: -If the affinity of a material is negative, that material will most probably be a receiver of electrons. If the affinity of a material is positive, that material will most probably be a donor of electrons.
Detailed explanation-3: -Can protons also be transferred? Explain why or why not? are rubbed together. Protons cannot be transferred, because they are too large.
