Question
Hulk tried to move the wall of a fortress, but unfortunately he was unable to do it. But he applied a very large amount of force to do so, hence work done is positive.
Answer: Option B
:
B
Work done by a force is defined as the product of force and displacement of the body along the direction of force. Since Hulk was unable to move the wall, the displacement is zero and irrespective of the large amount of force he applied, work done will be zero.
