electrons accelerated from rest through a potential difference of 25 kV. What is the final speed of
the electrons?
Provide the answer: .

The electrodes of a two-electrode lamp (diode) are filament-shapedradius R1 = 0.1 mm (cathode) and a cylinder coaxial with it with radius R2 = 2 mm (anode). Voltage U = 100 V is applied to the electrodes.Find the force F that the electron will experience when it is at a point 1 mm from the cathode axis.
An electron has an initial velocity of 2.4x106 m/s in the +x direction. It enters a uniform
electric field E = 397 N/C which is in the +y direction. What is the ratio of the y-component of
the velocity of the electron to the x-component of the velocity after traveling 5 cm in the +x
direction in the field? (Your result must include 2 digit after the decimal point and maximum of
5% of error is accepted in your answer. Take elementary charge 1.6x10-19 C and take mass of
electron 9.1x10-31 kg.)
