Solution:
Assuming $F$ to be the force applied to a body and $d$ to be the distance travelled by the body in the direction of force applied.
Energy ( $E$ ) is given by:
$E=F\cdot d\Rightarrow F=\frac{E}{d}$
so unit of force is= $Erg-m^{- 1}$
Energy ( $E$ ) is given by:
$E=F\cdot d\Rightarrow F=\frac{E}{d}$
so unit of force is= $Erg-m^{- 1}$
