It is not a way to charging an object.
Contact or Friction
Induction
Grounding
Wireless
Charging by contact consist in
One object a net electric charge by placing it in contact with another object that is already neutral
One object a net electric charge by placing it in contact with another object that is already conductor
One object a net electric charge by placing it in contact with another object that is already charged
One object a net electric charge by placing it in contact with another object that is already isolator
Charging by friction consist in
charge two non-conducting bodies by contact them with each other vigorously
charge two conducting bodies by rubbing them with each other vigorously
charge two non-conducting bodies by rubbing them with each other vigorously
charge two non-conducting bodies by induction them with each other vigorously
Charging by induction consist in
the charged particle is held near an untouching and heated material that is grounded on a neutrally charged material.
that charges an object without actually touching the object to any other charged object
that charges an object touching the object to any other charged object.
the charged particle is held near an semi-conductive material that is grounded on a neutrally charged material.
Charging by grounding consist in
the movement of protons between the charged object and the ground
the movement of electrons between the charged object and the sky
the movement of electrons between the charged object and the wet ground
the movement of electrons between the charged object and the ground

nonsense! None of these describe what 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 do not occur during the process?
Electrons are transferred from the sphere to the rod.
Positive electrons are moved between the two objects.
The metal sphere loses electrons
The overall charge of the system is conserved
