00:00The question says which of the following is smallest unit A mm B Angstrom C Fermi D meter

00:15is 1 meter is equal to 10 raised power 3 millimeters and 1 meter is equal to 10 raised power 10 angstrom

00:29and 1 meter is equal to 10 raised power 15 femtometers or we can also write as 1 millimeter

00:43is equal to 10 raised power minus 3 meters and 1 angstrom is equal to 10 raised power

00:50minus 10 meters and 1 Fermi is equal to 10 raised power minus 15 meters because Fermi

00:58is equal to femtometer it means meter is greater than millimeters and millimeter is

01:06greater than angstrom and angstrom is greater than Fermi as the quantity having greater negative

01:17power then its value will be less so the power of Fermi is 10 raised power minus 15 so Fermi

01:29is smaller than angstrom angstrom is smaller than millimeter and millimeter is smaller

01:36than meter so Fermi is smallest than all the others so the correct option will be C Fermi

01:44for Fermi
