During your studies, you observed discharge tubs containing a Maltese Cross, a wheel and a fluorescent display screen. Briefly describe which property of electrons each of these discharge tubes demonstrate.

cross : electrons can me stopped with a uniformly dense material
wheel : electrons carry a momentum/force/energy in them to push the wheel

fluorescent screen display: a magnet brought close to it causes the cathode ray to deflect. And applying electric plates causes it to deflect. it shows that cathode rays are made up of moving charged particles...??

cross: casts a shadow -> travels in a straight line.
wheel: makes it move -> mass and momentum.
fluorescent screen: can fluoresce -> has energy.
