Question

Two springs have spring constant kA and kB and kA > kB . 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

Tardigrade Admin · Accepted Answer

Work done in stretching ( W )= stiffness of spring ∵ kA>kB, WA>WB

Q. 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

more in spring $A$

more in spring $B$

equal in both

nothing can be said

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

Q. Two springs have spring constant kA​ and kB​ and kA​>kB​ . The work required to stretch them by same extension will be

more in spring A

more in spring B
