what is a difference between relative and absolute mass or charge??????????
| Absolute mass and charge is an exact and experimentally determined quantity. Example:The absolute mass of a proton is 1.6 x 10-27 Kg. The absolute charge of a proton is 1.6 x 10-19 Coulomb. |
Relative mass and charge is a comparitative quantity which is calculated by referring a known quantity. Example: the relative mass of a proton is 1u. The relative charge of a proton is +1 |
