Answer:
to hold the pail, the person would have to apply force F in the vertical direction (upwards irrespective of whether it is held by a rope or held on the person’s hand).
The person moves forward so the displacement of the person (and the pail) is horizontal while the force is vertical.
Work done by a force is the scalar product of the force vector and the displacement vector. Since these two vectors are perpendicular to each other, their scalar product will be zero. So work done will be zero.
