Problem
When a negatively charged plastic rod is brought near one end of an isolated neutral metal rod, which of the following best describes the immediate distribution of charge within the metal rod?
(a) − charges accumulate at the end closest to the plastic rod, while + charges move to the far end.
(b) The entire metal rod acquires a uniform negative charge because electrons are drawn onto it from the plastic rod.
(c) + charges accumulate at the end closest to the plastic rod, while − charges move to the far end.
(d) The end closest to the plastic rod becomes positively charged, and the remainder of the rod stays neutral.
