In the picture below, the rod is positively charged. Electrically speaking, water is a "polar molecule"; each water molecule can be imagined as a negative charge (the oxygen end) and a positive charge (the hydrogen end), each of approximate magnitude 2e, separated by an approximate distance of 2 x10-1" m. a) Explain how a charged rod can exert an electric force on water molecules that have zero net charge. Include a picture of a typical water molecule in the stream of water adjacent to the rod, showing its orientation relative to the rod. b) If the charge of the rod is +32 nC and that charge is located approximately 2.0 cm from a water molecule in the stream, what is the maximum possible net electric force that the rod could exert on the molecule?
