Question

What is the absolute mass of a proton?

• A. $9.1*{10}^{-27}kg$
• B. $1.67*{10}^{-27}\mathrm{kg}$
• C. $9.1*{10}^{-31}\mathrm{kg}$
• D. $\mathrm{None}\mathrm{of}\mathrm{these}$

Answer 1

The correct option is B

$1.67*{10}^{-27}\mathrm{kg}$

The explanation for the correct answer

Option B

The absolute mass of a proton = $1.67*{10}^{-27}\mathrm{kg}$

• Protons are positively charged subatomic particles.
• Charge of a proton = $1.6*{10}^{-19}\mathrm{C}$

The explanation for the incorrect answers

• Option A is incorrect.
• Option C Mass of electron = $9.1*{10}^{-31}kg$
• Option D is incorrect.

Conclusion: Hence, Option B is correct.
