Which of the following is not a correct statement?
- A Work done by conservative force is equal to negative change in potential energy
- B Total energy of system is always conserved
- C Work done by non-conservative force in a closed path is equal to zero
- D In stable equilibrium, the potential energy is minimum
Answer & Solution
Correct Answer
(C) Work done by non-conservative force in a closed path is equal to zero
Step-by-step Solution
Detailed explanation
When you do conservative work on an object, the work you do is equal to the negative change in potential energy Wc=−ΔU. As an example, if you lift an object against Earth's gravity, the work will be −mgh. Total energy of a system is always conserved, no matter…
