21. Instead, the point charges and their positions are optimized to best describe the electrostatics of the water molecule. 22. In the simplest case, the field is considered to be generated solely by a single source point charge . 23. Dipole moment between two point charges , the volume density of these is the polarization density "'P " '. 24. All the rest of the atom is beneath it and approximates to a point charge of + 1. 25. For example, the electric field associated with a point charge is infinite at the location of the point charge . 26. For example, the electric field associated with a point charge is infinite at the location of the point charge. 27. In 1925, Britannia became officially Britannia Heights United Church; part of a three-point charge including Bell's Corners and Fallowfield. 28. The electric potential due to a system of point charges is equal to the sum of the point charges 'individual potentials. 29. Derrick Sharp's 3-pointer midway through the last quarter cut Spain's lead to four at 61-57, and sparked Gasol's points charge . 30. Due to Earnshaw's theorem no static arrangement of classical electrostatic fields can be used to stably levitate a point charge .
