• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...

And explain why please. Problem 3.5 A stream of electrons (mass me and charge e) is accelerated (roughly from rest) through a potential difference created by a power supply of some EMF E. It then enters a region containing a magnetic field of strength B, as well as a pair of parallel plates of some separation h, which are charged by the same power supply. The strength of the power supply is then tuned until the electron stream continues through...
In the figure, an electron accelerated from rest through potential difference V_1 = 1.02 kV enters the gap between two parallel plates having separation d = 26.5 mm and potential difference V_2= 171 V. The lower plate is at the lower potential. Neglect fringing and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the gap?
Electric and Magnetic Fields a) An electron (initially at rest) is accelerated from the negative plate to a positive plate that is located 20 cm away. The voltage across the plates is 200 V. What is the velocity of the electron as it reaches the positive plate? b) Now if the electron passes through a small hole in the positive plate (travelling right) and enters a magnetic field (B = 0.5 T) that is directed perpendicular to the direction of...
