If the charge is on the positive side, an electron in a magnetic field will move toward the fixed positive charge. As the potential energy increases, the electron’s mechanical energy decreases. In general, an electron will lose electrical potential energy when it moves from i to f. However, there are a few exceptions. A few of them are discussed below.
The electric potential is the change in electrical charge per unit mass. The potential difference between two points is defined by the difference in potential energy. The voltage is a common symbol for potential energy. The difference in kinetic energy is known as the electromotive force between negative and positive particles. When the electron is moving from f to i, the kinetic energy of the positive particle decreases while that of the negative particle increases.
Electric potential energy is not affected by gravity. If the electron moves from i to f, its electric field decreases as the charge moves toward f. If the charge moves away from the nucleus, its energy is converted back to kinetic energy. The voltage of an evacuated tube is 5 kV. As an example, an electron is accelerated from rest to a maximum speed by a copper plate.
An electron in motion has a negative charge. The lower the charge, the lower its electric potential energy. As the electron moves away from the electric field, it is slower. Therefore, the electric potential energy changes with its movement away from the electromotive force. As the electron moves away from the field, it loses its momentum. The opposite is true. When the electron is traveling toward f, its electric potential energy increases.
During the motion of an electron, the electric field points in the opposite direction to the electrostatic potential. The Coulomb force pulls the electron toward the proton, while the centripetal force pulls the electron away from it. The difference between the two forces is the difference in the amount of kinetic and potential energy. The latter has more energy, thus causing the motion to be more stable.
The electric field vector points in the opposite direction of the gradient of the electric potential. If the charge is moving towards the negative end, the electric field is at the opposite end of the spectrum. As a result, the positive charge moves toward f, while the negative charge is pushed away from f. The corresponding force is the same for both. The kinetic energy of the electrons is equal, but the electrical field has an opposite sign.
As the electron moves from i to f, the electric field increases at point P. During this process, the electron moves downhill, and its qe increases from i to f. The kinetic energy is the energy that is given to an electron. So, an ion has a kinetic and a negative charge. During this time, the charge is at its lowest.
The electric potential energy of an electron decreases as the electron moves from i to i. When it moves from f to f, the charge has the same direction as the positive point. As the charge is moved from i to f, the electric potential energy increases. The work that the positive charge does to move the electron from i to f reduces as the negative charge approaches i.
During the move from i to f, the electric field vector points to the opposite of the direction of the electric potential. If the electron is accelerating at a constant speed, the electric field is increasing in the direction that the electron moves from i to f. The final charge has a negative charge, while the electron is moving from i to f.
