[amp_mcq option1=”Imaginary work” option2=”Negative work” option3=”Virtual work” option4=”None of these” correct=”option3″]
The correct answer is: C. Virtual work.
Virtual work is the work imagined to be done by a force when a body in equilibrium undergoes an infinitely small displacement. It is a concept in physics that is used to analyze the equilibrium of a system.
Imaginary work is not a real physical quantity. It is a mathematical concept that is used to simplify the analysis of a system.
Negative work is work that is done in the opposite direction of the force. It is a real physical quantity.
None of these is not a correct answer.
