Early black-and-white television sets used an electron beam to draw a picture on the screen. the electrons in the beam were accelerated by a voltage of 3.0 kv m kv; the beam was then steered to different points on the screen by coils of wire that produced a magnetic field of up to 0.67t
a
what is the speed of electrons in the beam?
b
what acceleration do they experience due to the magnetic field, assuming that it is perpendicular to their path? what is this acceleration in units of g image for early black-and-white television sets used an electron beam to draw a picture on the screen. the electrons in?
c
if the electrons were to complete a full circular orbit, what would be the radius?
