attract; like
attract, opposite
repel; like
repel; opposite
Which statement is true of a positively charged object?
Positively charged objects do not contain any electrons.
Positively charged objects do not contain neutrons or electrons.
There is a lack of electrons on a positively charged object.
The protons and the electrons are both positively charged on such objects.
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
