Let the two springs A and B be such that`K_(A)gtK_(B)` , On which spring will more work has to be done if they are stretched by the same force ?

Text Solution

Verified by Experts

`F=K.x` so `x=(F)/(K)`
for same `F,W_(A)=(1)/(2)(F^(2))/(K_(A))`
and `W_(B)=(F^(2))/(2K_(B)`
`therefore (W_(A))/(W_(b))=(F^(2))/(2K_(B))`
`AsK_(A)gtK_(B) so W_(A) lt W_(B)`.
