Question

Which of the following is the smallest unit? (1) Millimetre (2) Angstrom (3) Fermi (4) Metre

February 4, 2024

Answer

Fermi

Reason — Fermi is 10^-15th part of a metre.

i.e., 1 fermi = 10^-15 m, hence it is the smallest unit.

Angstrom = 10^-10th part of a metre.

Millimetre = 10^-3th part of a metre.
