Keisha writes that if an object has any external forces acting on it, then the object can be in dynamic equilibrium but not static equilibrium. Which statement best describes Keisha’s error? An object that is not moving is always in static equilibrium. An object that is moving must be in dynamic equilibrium. An object in either state of equilibrium must have no forces acting on it. An object in either state of equilibrium must have no net force acting on it.

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?
