A force of $200\text{N}$ displaces a body by $4\text{m}$, calculate the work done (in $\text{J}$).

Work done ($W$) is calculated as the product of the force ($F$) applied and the displacement ($d$) in the direction of the force:
$$W=F\times d$$
Given:Force, $F=200\text{N}$ Displacement, $d=4\text{m}$ $
$W=200\text{N}\times 4\text{m}=800\text{J}$ $
