Answer 1

Answer:

The diagram gives more clarity of the 3x extension and the final work done is 3kx

(D) None of these

2K​:-

The answer directly from the equations and the theory is 3Kx as the spring had an spring constant of K and was extended 3x which is the work done stored into the spring force energy as that is the work done which answers the problem.

Answer:-The diagram gives more clarity of the 3x extension and the final work done is 3kx done.
