Question 1

J.J. Thomson Cathode Ray experiment facts

Answer 1

electrons traveled from negatively charged cathode to positively charged anode
electrons traveled in straight lines
electrons were material independent
electrons are negatively charged
measured the charge-to-mass ratio of the cathode ray particles by deflecting them using electric and magnetic fields
-1.76 × 10^3 C/g (Coulombs per gram) is the charge-to-mass ratio for electrons
