A positively charged cloud passes over a tall steel-framed building. A charge is induced on the building by the cloud because charge carriers (electrons) flow through the building.
What charge is induced on the building and in which direction do the charge carriers (electrons) move?
positive induced charge, electron flow from the building to earth
positive induced charge, electron flow from earth to the building
negative induced charge, electron flow from the building to earth
negative induced charge, electron flow from earth to the building
