A simple and common technique for accelerating electrons is shown in Figure 18.55, where there is a uniform electric field between two plates. Electrons are released, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to continue moving. (a) Calculate the acceleration of the electorn if the field strength is 2.50104 N/C. (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.
What is the potential 0.530 x 10-10 m from a proton (the average distance between the proton and electron in a hydrogen atom)?
In different experimental trials, an electron, a proton, or a doubly charged oxygen atom (O--), is fired within a vacuum tube. The particle's trajectory carries it through a point where the electric potential is 40.0 V and then through a point at a different potential. Rank each of the following cases according to the change in kinetic energy of the particle over this part of its flight from the largest increase to the largest decrease in kinetic energy. In your ranking, display any cases of equality, (a) An electron moves from 40.0 V to 60.0 V. (b) An electron moves front 40.0 V to 20.0 V. (c) A proton moves from 40.0 V to 20.0 V'. (d) A proton moves from 40.0 V to 10.0 V. (e) An O-- ion mines from 40.0 V to 60.0 V.
Two charges 20Cand+2.0C are separated by 4.0 cm on the z-axis symmetrically about origin, with the positive one uppermost. Two space points of interest and P1andP2 are located 3.0 cm and 30 cm from origin at an angle 30 with respect to the z-axis. Evaluate electric potentials at P1andP2 and in two ways: (a) Using the exact formula for point charges, and (b) rising the approximate dipole potential formula.
