1 a) A uniform electric field of 2.0 x 102 N/C is applied between the anode and the cathode. If an electron is injected in the region of a uniform field along the x-axis, what is the velocity of the electron when it reaches the anode assuming a separation between the anode and cathode of 4 cm, and initial kinetic energy is negligible.
b) If the electron was injected in the region along the y-axis with the initial velocity vo= 3 x 106 m/s, and the length of the plate l= 0.1m. (a) Find the acceleration of the electron in the electric field. (b) Find the time it takes the electron to travel through the region of the electric field. (c) What is the displacement x of the electron while in the electric field? Will it strike the plate? Why/why not?
