springs A and B are identical except that A is stiffer than B i.e. the force constant is k(A) k(B) . in which spring is more work done if:

1. they stretch by same amount

2. they are stretched by same force

(2) When they are stretched by the same force.

In this case F (Force is the same)

(1) When stretched by the same amount, i.e. the extensions in both the springs is the same.
