Answer is option A) i.e Joule
The work done when a force is expressed in Newton and the distance in metre is expressed in Joule.
This is because joules are equivalent to the work done (or energy expended) by a force of one newton (N) acting over a distance of one metre.
The equation used to calculate the work is Work = Force × Distance, where force is measured in newtons and distance in metres. Therefore, one joule is the energy required to move an object over a distance of one metre, when a force of one newton is applied.
