Arrange the four graphs in descending order of total work done; where \(W _{1}, W _{2}, W _{3}\) and \(W _{4}\) are the work done corresponding to figure \(a , b , c\) and d respectively.
- A \(W _{3}> W _{2}> W _{1}> W _{4}\)
- B \(W _{3}> W _{2}> W _{4}> W _{1}\)
- C \(W _{2}> W _{3}> W _{4}> W _{1}\)
- D \(W _{2}> W _{3}> W _{1}> W _{4}\)
Answer & Solution
Correct Answer
(A) \(W _{3}> W _{2}> W _{1}> W _{4}\)
Step-by-step Solution
Detailed explanation
Work done \(=\) area under \(F - x\) curve. Area below \(x\) -axis is negative and area above \(x\)-axis is positive. so, \(W _{3}> W _{2}> W _{1}> W _{4}\)
