• positive

• negative

• neutral

• imaginary

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

• negatively charged

• positively charged

• neutral

• either negatively charged or positively charged , depending whether the fur is always moved in the same direction or moved back and forth.
