In the inside of a TV set an electron is accerlerated by apotential difference of 20 kV in an evacuated tube. It is thenpassed through an uniform magnetic field of 100 mT which deflectsit to the desired position on the screen.
1) Draw a diagram showing the path of the electron as it passesfrom the electron source to the screen.
2) After passing through the accelerating potential, what is thekinetic energy of the electron in eV? In joules?
3) What is the speed of the electron just before it enters themagnetic deflecting field?
4) What will be the radius of curvature of its path in thefield?
