Calculate the work done by a person who exerts a force of 200.0 n in the horizontal direction on a box that moves 10.0 meters along a ramp that makes an angle of +30.0o with the horizontal, moving the box at a constant speed. note: do not include the work done on the person, only on the box. a. 1000 jb. 1730 jc. 3430 j

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?
