Assume the field is uniform inside the capacitor and zero outside the the gap between them. capacitor. Express your answer with the appropriate units. E tugs '5 0 O ? Ay= Value Units Muest Answer Provide Feedback Next > Review Part A An electric field can induce an electric dipole in a neutral atom or molecule by pushing the positive and negative charge in opposite directions. The dipole moment of an induced dipole is directly What are the units of a? proportional to the electric field. That is, p = QE, where a is called the polarizability of the molecule. O C's2m/kg A bigger field stretches the molecule farther and causes a larger dipole moment. O C's2m2 /kg O C2 /kg O C2 s2 / kg Submit Request Answer Part B An ion with charge q is distance r from a molecule with polarizability o. Find an expression for the magnitude of the force Fion on dipole . Express your answer in terms of the variables q, r, a and appropriate constants. IVO AEd ?

Asecond point charge with charge q; = -4.10 ,uC moves from the point ( 0.170 m , 0) to the point (0.235 In , 0.290 In). How much work W is done by the electric force on the moving point charge? 1 47mg ' Express your answer in joules. Use is = 8.99x109 N - m2 /C2 for Coulomb's constant: k = b View Available Hint(s)
