A salvage ship is attempting to raise an iron anchor off the ocean floor. The anchor has a mass of 560kg and the density of iron is 7800 kg/m^3. The cable used to lift the anchor can support a weight of 5000N before breaking. Use 1025kg/m^3 as the density of sea water . a)Will the cable be able to support the anchor while it is completely submerged? b)What is the percentage of the anchor will be out of the water when the cable breaks?​

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?
