The dipole moment of the water molecule (H2O) is 6.17x10^-30 C · m. Consider a water molecule located at the origin whose dipole moment vector p points in the +x-direction. A chlorine ion (Cl−), of charge −1.60 *10-19 C, is located at x = 1.34 *10-9 m.
Find the magnitude and direction of the electric force that the water molecule exerts on the chlorine ion.
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 E = p/2πε0y3 can be used, where p is the dipole moment, and y is the distance between ions.
A) What is magnitude______N
B) Direction? +x-direction or -x-direction
C) Is this force attractive or repulsive?
