 One end of a light spring of spring constant k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacement, the work done by the spring is . The possible cases are:
  • a)
    The spring was initially compressed by a distance x and was finally in its natural length
  • b)
    It was initially stretched by a distance x and finally was in its natural length
  • c)
    It was initially in its natural length and finally in a compressed position.
  • d)
    It was initially in its natural length and finally in a stretched position.
Correct answer is option 'A,B'. Can you explain this answer?

One end of a light spring of spring constant k is fixed to a wall and ...
Stored elastic potential energy of spring =1/2​kx2 where x is compression or elongation of spring from its natural length. In this position the spring can do work on the block tied to it, which is equal to 1/2​kx2, so both option (a) & b are correct.
