If the force is in the right range ... not too strong and not too
weak ... then a bathroom scale can be used to measure it.
If the force is huge, then you'd need a truck scale.
If the force is small, then you'd need a laboratory balance.
Answer: There is not work done at the door because the door did not move.
Explanation: Work is defined as the movement done by a force.
So if you move to apply a force F in an object and you move it a distance D, the work applied on the object is
W = F*D
In this case, the secret agent pushes against the door, so there is a force, but the agent does not move the door, so D = 0, so there is no motion of the door, which implies that there is no work done at the door.
