The total electric field E consists of the vector sum of two parts. One part has a magnitude of E1 = 1248 N/C and points at an angle θ1 = 40° above the +x axis. The other part has a magnitude of E2 = 1578 N/C and points at an angle θ2 = 53° above the +x axis. Find the magnitude and direction of the total field. Specify the directional angle relative to the +x axis.

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 p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that 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. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
