Physics

An electron is accelerated inside a parallel plate capacitor.The electron leaves the negative plate with a negligible initialvelocity and then after the acceleration it hits the positive platewith a final velocity β. The distance between the plates is 14.2cm, and the voltage difference is 146 kV. Determine the finalvelocity β of the electron using classical mechanics. (The restmass of the electron is 9.11×10-31 kg, the rest energyof the electron is 511 keV.)
7.559×10-1

What is the final velocity β of the electron if you userelativistic mechanics?
