A molecule is represented by a charge -2q at the origin and charges +q at b1 and b2, where | b1 | = | b2 | = b.
a) Find dipole moment of the molecule?
b) For a water molecule, b = 0.958 * 10^-10m and the angle between b1 and b2 is theta = 105 degrees. If |p| = 6.14* 10^-30 C*m, what is q (as a multiple of the charge, e , of a single electron)?
