(A) Work is defined as the product of force and displacement. The $SI$ unit of work is the joule $(J)$,which is equivalent to $1 	ext{ N} \cdot 	ext{m}$.In the $CGS$ (centimeter-gram-second) system,the unit of force is the dyne and the unit of displacement is the centimeter $(cm)$.Therefore,the $CGS$ unit of work is the erg,where $1 	ext{ erg} = 1 	ext{ dyne} \cdot 	ext{cm}$.$1 	ext{ joule} = 10^7 	ext{ ergs}$.

The $CGS$ unit of work is:
