D
velocity
Explanation: 

Detailed explanation-1: –Absolute mass is the term used to describe mass of subatomic particles like protons, neutrons, electrons, etc.

Detailed explanation-2: -Solution. The absolute mass of an electron is approximately 9.108 × 10–28. Its absolute charge is 1.6 × 10–19 C.

Detailed explanation-3: -Absolute mass or Actual atomic mass: It is found that, the actual atomic mass of a carbon-12 atom is equal to 1.9926×10−23 1.9926 × 10-23 g. Thus by multiplying the relative atomic mass with 1.6605 × 10-24g we can get the absolute or actual mass of an atom.

Detailed explanation-4: -Therefore, the absolute mass of proton is. 6 × 10-27 kg and absolute mass of proton is. 6 × 10-19 coulombs .

Detailed explanation-5: -The absolute mass of an electron is 9 × 10-31 kg .
