The end of the neutral rod which is the closest part to the charged rod would acquire a negative charge.
Explanation:
One of the rods is positively charged and one of them is neutral.
And the important part is that <u>they do not touch one another</u>, but get close to each other.
In this case, the end of the neutral rod which is the closest part to the charged rod would acquire a negative charge. This is because of the Coulomb's Law. The opposite charges exert an attractive force to each other. The positive charges attract the negative charges on the neutral rod.
