Problem
While charging a metal sphere by the procedure described, measurements show that 2.5nC of charge flows from Earth onto the sphere during the brief grounding step. After the ground wire is disconnected and the inducing rod is removed, determine the magnitude and sign of the net charge that remains on the sphere.
