Can a neutral conductor have separated positive and negative regions by induction?

A negative rod is brought near a neutral conductor. Which sign is induced on the near side?

During induction without contact or grounding, does the conductor's net charge change?

A positive rod is near a neutral metal sphere. The sphere is grounded while the rod remains nearby. Do electrons flow from ground to sphere or from sphere to ground?

A negative rod charges a neutral conductor by induction using grounding. What sign is left on the conductor after the ground is removed and then the rod is taken away?

A neutral conductor has induced charges \(+9\,\mathrm{nC}\) on the near side and \(Q_{\mathrm{far}}\) on the far side while isolated. Find \(Q_{\mathrm{far}}\).

Describe the correct order of steps to charge a neutral conductor negatively by induction using a positive rod and a ground connection.

A charged rod attracts a neutral conductor. Explain why attraction can occur even though the conductor's net charge is zero.

A student grounds a neutral conductor first, removes the external charged rod while the ground is still attached, and only then disconnects the ground. Predict the final net charge and identify the failed induction step.

A positive rod is held near two touching neutral metal spheres. The spheres are separated while the rod remains, then the rod is removed. Determine the final signs on the near and far spheres, and explain why total charge is conserved.
