Cathode Ray tubes allow a manipulation of a stream of charged particles
*CRT - consist of evacuated glass tube containing two electrodes
*High voltage is applied across electrodes - stream of negatively charged particles from cathode to anode
*Structures built around the cathode (e.g. electric plates and magnetic coils) can be used to manipulate CR
Charge particles produce an electric field
*Electric field exists in any region that an electrically charged object experiences a force
*A charge in an electric field experiences a force F = Eq
Oppositely charged parallel plates
*Electric fiel…
