6 Calculate the energy gained by an electron when it is accelerated through a potential difference...
The electronvolt is the energy knetic energy gained by an electron when it is accelerated in a potential difference. I have two questions involving eV 1. Does it mean that inside of the battery there is an electric field and this electric field will accelerate the electron, when the electron pass through it? It mean that in an open circuit there is no knetic energy involved? 2. the reason we say " accelerated in a potential difference" is because the...
2.032 4. An electron is accelerated through potential difference of 150 V from rest and then enters a region of uniform magnetic field traveling perpendicular to the field. The magnitude of magnetic field is 0.50 T. a) What is the magnitude of magnetic force acting on the electron (5.8x10-14 N), and b) what is the radius of the path?

An electron is accelerated from rest through a potential difference that has a magnitude of 2.70 × 107 V. The mass of the electron is 9.11 × 10-31 kg, and the negative charge of the electron has a magnitude of 1.60 × 10-19 C. (a) What is the relativistic kinetic energy (in joules) of the electron? (b) What is the speed of the electron? Express your answer as a multiple of c, the speed of light in a vacuum.
