Problem
Which of the following most likely occurs immediately after a small positively charged aluminum sphere is connected to Earth by a metal wire?
(a) Electrons flow from the sphere down the wire to Earth until its excess positive charge is removed.
(b) Protons are drawn from Earth up the wire to the sphere until the sphere is neutral.
(c) Electrons flow from Earth up the wire to the sphere until its net charge becomes zero.
(d) Electrons flow from Earth to the sphere until the sphere acquires an equal-magnitude negative charge.
