Task $2$: 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.

$($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.
