Two springs have spring constant k_ A and k_ B and k_ A >k_ B . The work required to stretch them by same extension will be

Options

  1. Amore in spring A
  2. Bmore in spring B
  3. Cequal in both
  4. Dnothing can be said

Correct answer

A. more in spring A

Step-by-step solution

Work done in stretching ( W )= stiffness of spring k_ A >k_ B , W_ A >W_ B
