1. The problem statement, all variables and given/known data Electrons, which evaporated from the filament accelerated in homogeneous electric field that was created by using two parallel metal plates, connected to the voltage V = 1 kV. The resulting stream of electrons is deviated from the initial direction for a φ = 15 ° in electrical field between two parallel flat surfaces. The length of the plate, in the direction of the initial movement of electrons, is s = 10 cm and the distance between the plates is d = 2 cm. What is the voltage V' between the two plates? 2. Relevant equations E= V/d ΔV= V’ – V ΔV= -E*d*cos φ 3. The attempt at a solution E= V/d E= 1000 v/ 0.02 m E= 50000 V/m ΔV= -E*d*cos φ V’ – V= -E*d*cos φ V’ – 1000 V= -50000 V/m*0.02m*cos15º V’= -965.9 V – 1000 V V’= 34.1 V Are my calculations correct? Thank you for helping!
