alleryStart learning →Mass of a proton compared with that of an electron is:
AEqual
BAbout 100 times more
CAbout 10 times less
DAbout 1836 times more
Answer & Solution
Correct answer: D. About 1836 times more
1. Electron mass is about 9.11 * 10^-31 kg.
2. Proton mass is about 1.67 * 10^-27 kg.
3. Ratio is roughly 1836.
4. So a proton is about 1836 times heavier than an electron.
