when a metal plate is gives a positive charge , which of the following is taking place ?

• Protons are transferred from the plate to another object.

• Electrons are transferred from the plate to another object.

• Electrons are transferred from plate to another object, and protons are also transferred to the plate from another object

• it depends on whether the object conveying the charge is a conductor or insulator
