Springs Aand B are identical except that A is stiffer than B. In which spring more work is done if(a) both are stretched by same amount ? (b) both are stretched by the same force ?

(i) Work done in stretching a spring of force constant k through a distance x, i.e., `W = 1/2 kx^2`
Thus, `(W_A)/(W_B) = ((1//2) K_A x^2)/((1//2) k_B x^2) = (k_A)/(k_B) , "As" k_A > k_B, W_A > W_B`.
