Question : Which is the most suitable unit for expressing nuclear radius?
Option 1: Micron
Option 2: Nanometre
Option 3: Fermi
Option 4: Angstrom
Correct Answer: Fermi
Solution : The correct answer is Fermi.
The nuclear length is quantified using the unit called the "fermi" (fm), where 1 fermi is equivalent to 10 -15 meters. This unit, originally named after the Italian physicist Enrico Fermi, has been replaced by the SI term "femtometer" (symbol: fm). Consequently, one fermi is now synonymous with one femtometer, making it the most suitable unit for expressing nuclear radii.
