1. If the object is not grounded, the nearby charge will induce equal and opposite charges in the object.
2. If any part of the object is momentarily grounded while the inducing charge is near, a charge opposite in polarity to the inducing charge will be attracted from ground into the object, and it will be left with a charge opposite to the inducing charge.
