The ratio of charge to mass of an electron in coulombs per gram was determined by J.J. Thomson. He determined this ratio by measuring the deflection of cathode rays in electric and magnetic fields. What value did he find for this ratio?
View answer and explanation
Correct option: A
−1.76×108-1.76 \times 10^8 coulombs/g
Option A (−1.76×108-1.76 \times 10^8 coulombs/g) is correct because it represents the experimentally determined charge-to-mass ratio of an electron.
