12. Curling is a sport in which players push large stones across smooth ice. Three curling stones that have the same mass were sliding across the ice. They were
each pushed by a player, but not all from the same direction. Each curling
stone changed speed as a result of being hit. Use the information in the
diagram to answer.
Which curling stone(s) experienced the strongest force when hit? How
do you know?

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?
