In a resonating pipe that is open at one end and closed at the other end, there is a displacement node at the closed end and a displacement antinode at the open end.

are displacement antinodes at each end.

are displacement nodes at each end.

is a displacement node at the open end and a displacement antinode at the closed end.

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?
