Answer 1

Answer:

no work

Explanation:

$w = \: f \: d \: x \: cos(?) \\ where \: dx \: = 0 \: \\ so \: w \: = 0$

Answer 2

Answer:

Zero work

Explanation:

Work is  an action that requires the use of one's faculties or strength; a: a habitual activity persons who are seeking for job participate in to make a living. b: a particular responsibility, work, or assignment that is frequently a component or stage of a bigger activity.

Mathematical equation of work is given by

      w = F.dx cos∅

 where ∅ is the angle between force F and displacement dx

   Here the displacement of the body dx = 0

⇒Work done = 0

∴ work when a boy sits on a place in study for the whole night he does is Zero.
