18 Questions
What is the result of bringing a negatively charged object close to a neutral metal object?
The electrons are repelled on the other side away from the negatively charged object.
What is the method of charging that occurs when two objects are in physical contact with each other?
Charging by conduction
What is the purpose of the negatively charged rod in Figure 1.1.7?
To induce positive charges in the side of the sphere near the rod
What is the result of charging an object by conduction?
The object becomes negatively charged.
What is the principle behind charging by induction?
The separation of charges within an object due to an external influence.
What is a characteristic of charging by friction?
It involves the transfer of charges between two objects.
What determines the tendency of materials to acquire charge when rubbed against each other?
Electron affinity
What is the ranking of materials based on their tendency to acquire charge called?
Triboelectric series
What is the method of charging where a charged object is in contact with a neutral object?
Charging by conduction
Why does plastic become negatively charged when rubbed with fur?
Because plastic has a higher electron affinity than fur
