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
- A more in spring \(A\)
- B more in spring \(B\)
- C equal in both
- D nothing can be said
Answer & Solution
Correct Answer
(A) more in spring \(A\)
Step-by-step Solution
Detailed explanation
Work done in stretching \((\mathrm{W})=\) stiffness of spring
\(\because\) \(k_{A}>k_{B}, W_{A}>W_{B}\)
\(\because\) \(k_{A}>k_{B}, W_{A}>W_{B}\)
