The minus sign shows that the electric field is directed from the region of higher potential to the region of lower potential.
I n three dimensions, the electric field equals the negative gradient of the potential. An electron leaves the surface of A with a velocity v, in the direction toward B. How much speed v will it have if it reaches B? From the definition, Eq. Assume, therefore, that the orbit of t h e electron in this planetary model of the atom is a circle, the nucleus being supposed fixed in space.
I t is a simple matter to calculate its radius in terms of the total energy W of the electron. The force of attraction between the nucleus and the. Then, according to the conservation of energy, where the energy is in joules. Combining this expression with produces which gives the desired relationship between the radius and the energy of the electron. This equation shows that the total energy of the electron is always negative. The negative sign arises because the potential energy has been chosen to be zero when r is infinite.
This expression also shows that the energy of the electron becomes smaller i. The foregoing discussion of the planetary atom has been considered only from the point of view of classical mechanics. However, an accelerated charge must radiate energy, in accordance with the classical laws of electromagnetism.
If the charge is performing oscillations of a frequency f, the' radiated energy will also be of this frequency. Hence, classically, it must be concluded that the frequency of the emitted radiation equals the frequency with which t h e , electron is rotating in its circular orbit.
