Answer 2

Answer:

e/m ratio of electron is 1.76 × 10^8 c/g or 1.76 × 10^11 c/kg

e/m ratio of proton is 9.58 × 10^4 c/g or 9.58 × 10^7 c/kg

How to find e/m ratio of proton

Proton charge = 1.602 × 10^-19

Proton mass = 1.672 × 10^-24

e/m ratio also means charge by mass ratio

= 1.602 × 10^-19 / 1.672 × 10^-24

= 0.958 × 10^5

= 9.58 × 10^4
