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?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
