Question
In a tug of war, one team is slowly giving way to the other. What work is being done and by whom?
Solution
The net force acting on the losing team is the resultant of the forces applied by the two teams. So, it undergoes displacement. Positive work is done by the winning team on the losing team.
The force applied by the losing team is zero. This is because the winning team does not move. The losing team does not displace from its position and hence work done by the losing team is zero.
