During a laboratory experiment, a student brings a positively charged glass rod close to a initially neutral conducting sphere fixed on an insulator. The glass rod does not make contact with the sphere. Then, the student touches the sphere with a grounded wire. Considering this process of electrification, determine the final electric charges present in the sphere and the glass rod. (assume that the initial electric charge of the glass rod is +8Q)

The sphere becomes negatively charged with -8Q and the glass rod remains with a charge of +8Q.

The sphere becomes negatively charged with -2Q and the glass rod remains with a charge of +8Q.

The sphere becomes positively charged with +4Q and the glass rod remains with a charge of +8Q.

The sphere remains neutral and the glass rod remains with a charge of +8Q.

The sphere becomes negatively charged with -4Q and the glass rod remains with a charge of +8Q.
