a. Represent atoms by small circles that can be charged,neutral, or have a permanent dipole moment represented by an arrowwithin the circle. Show in a sketch how two such atoms interact inthe following cases (show the direction of the force and/or torqueon each atom): (i) one charged and one neutral atom; (ii) onecharged and one polar molecule; (iii) and both dipolar moleculeswith parallel dipoles.
b. For a parallel plate capacitor, how does the capacitancechange if (i) the plate areas are doubled, (ii) the voltage acrossthe capacitor is halved, (iii) the plate separation is halved, (iv)the material between the plates is changed to one with twice thedielectric constant, (v) the charge on the capacitor isdoubled?
