Detailed Solution

The above statement is False.
The child climbing the tree does more work than the student studying in his room. As the child does some displacement while the student does no displacement. And work is directly proportional to the displacement.
The correct statement would be As, work done, W= Force ×displacement
Here, the student is preparing for the exam in his study room, there is no displacement.
