Two springs A and B are identical to each other . The spring A is harder than the spring B . On which spring more work will be done if they are stretched by same force ?

Text Solution

Verified by Experts

`W=1/2 Kx^(2)`
`:.(W_(A))/(W_(B))=(K_(A))/(K_(B))` for same x
As `K_(A)gtK_(B)` so `W_(a)gtW_(B)`
