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 vector p points in the +x-direction. A chlorine ion (Cl−), of charge −1.60 10-19 C, is located at x = 1.34 10-9 m. Find the magnitude and direction of the electric force that the water molecule exerts on the chlorine ion. Assume that x 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 E = p/2πε0y3 can be used, where p is the dipole moment, and y is the distance between ions. A) What is magnitudeN B) Direction? +x-direction or -x-directionC) Is this force attractive or repulsive?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
