Can two equipotential lines cross? Explain.
No, two equipotential lines can not be crossed with each other as a point can never have two potential values.

(II) The dipole moment, considered as a vector, points from the negative to the positive charge. The water molecule, Fig. 17鈥�42, has a dipole moment \({\bf{\vec p}}\) which can be considered as the vector sum of the two dipole moments, \({{\bf{\vec p}}_{\bf{1}}}\) and \({{\bf{\vec p}}_{\bf{2}}}\) as shown. The distance between each H and the O is about \({\bf{0}}{\bf{.96 \times 1}}{{\bf{0}}^{{\bf{ - 10}}}}\;{\bf{m}}\). The lines joining the centre of the O atom with each H atom make an angle of 104掳, as shown, and the net dipole moment has been measured to be \({\bf{p = 6}}{\bf{.1 \times 1}}{{\bf{0}}^{{\bf{ - 30}}}}\;{\bf{C}} \cdot {\bf{m}}\). Determine the charge q on each H atom.

(II) It takes 18 J of energy to move a 0.30-mC charge from one plate of a \({\bf{15}}\;{\bf{\mu F}}\) capacitor to the other. How much charge is on each plate?
(II) A \({\bf{ + 35}}\;{\bf{\mu C}}\) point charge is placed 46 cm from an identical \({\bf{ + 35}}\;{\bf{\mu C}}\) charge. How much work would be required to move a \({\bf{ + 0}}{\bf{.50}}\;{\bf{\mu C}}\) test charge from a point midway between them to a point 12 cm closer to either of the charges?
A dielectric is pulled out from between the plates of a capacitor which remains connected to a battery. What changes occur to (a) the capacitance, (b) the charge on the plates, (c) the potential difference, (d) the energy stored in the capacitor, and (e) the electric field? Explain your answers.
Question: (II) How much energy is stored by the electric field between two square plates, 8.0 cm on a side, separated by a 1.5-mm air gap? The charges on the plates are equal and opposite and of magnitude \({\bf{370}}\;{\bf{\mu C}}\).
