Question

Determine e/m Value For Proton (e = Charge, m = Mass).

Answer 1

• The magnitude of the charge is the same for both proton and electron. Whereas, the mass of a proton is about 1850 times the mass of an electron. The magnitude of the charge is the same for both proton and electron.
• As a proton has a mass very much greater than the mass of an electron, the ratio e/m for a proton will be smaller than the corresponding value for an electron.
• Overall, e/m for an electron will be approximately 1850 times the e/m for a proton.
