Final answer:

When a positively charged insulating rod is brought near the end of a neutral conducting rod, the conduction electrons in the conducting rod will be attracted to the insulating rod. This results in a charge distribution on the conducting rod, with more negative charge near the insulating rod and more positive charge at the opposite end.

Step-by-step explanation:

When an insulating rod with uniformly distributed positive charge is brought near the end of a neutral conducting rod, the conduction electrons in the conducting rod will be attracted to the insulating rod. As a result, the conduction electrons will move towards the end of the conducting rod closest to the insulating rod, causing that end to become negatively charged. The opposite end of the conducting rod, farthest from the insulating rod, will have an excess of positive charge. This creates a charge distribution on the conducting rod, with more negative charge near the insulating rod and more positive charge at the opposite end.
