1.	Spring A and B are identical except that A is stiffer than B, i.e., Force constant k_(A)gtk_(B). In which spring is more work expended if they are stretched by the same amount ?
Answer» SOLUTION :`W=1/2Kx^(2)` `THEREFORE W_(A)/W_(B)=K_(A)/K_(B), "for some x"` `"as" K_(A)gtK_(B) "so" W_(A)gtW_(B)`
