The five-charge model below consists of the interaction between a molecule of oil, represented as two polarization charges, to the left, and a molecule of water, to the right. O H* H* 50 pm 100 pm 50 pm 100 pm (a) Draw a free-body diagram for the + charge of the oil molecule. Label each force, clearly linking each force with which part of the water molecule. Include an appropriate coordinate system with the x and y directions explicitly drawn. (b) Is the force of the two hydrogen ions on the + charge of the oil to be greater or less in magnitude than the force of the oxygen ion on the oil? Briefly explain without calculations. (c) Without doing any calculations, is the water molecule attracted to the oil molecule, or is the net force equal to zero? Explain.
