Compute each part of given question:
Question: The dipole moment of the water molecule (H2O) is 6.17 x 10-30 C.m. Consider a water molecule located at the origin whose dipole moment p points in the +x-direction. A chlorine ion (Cl-), of charge-1.60 x 10-19 C, is located at x=3.00 x 10-9 m. Assume that x is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used.
Part I: Find the magnitude of the electric force that the water molecule exerts on the chlorine ion.
Part II: What is the direction of the electric force?
Part III: Is this force attractive or repulsive?
Please explain your answer. I know substitution is involved so be sure to give a detailed explanation on that as well.
