An electron is accelerated inside a parallel plate capacitor. Theelectron leaves the negative plate with a negligible initialvelocity and then after the acceleration it hits the positive platewith a final velocity Ã. The distance between the plates is 13.5cm, and the voltage difference is 113 kV.
a) Determine the final velocity à of the electron using classicalmechanics. (The rest mass of the electron is 9.11Ã10-31 kg, therest energy of the electron is 511 keV.)
I got this answer, 6.65 * 10^1 But cant figure out part bbelow.
b) What is the final velocity à of the electron if you userelativistic mechanics?
