A uniform spring has an unscratched length L and a force constant k. the spring is cut into two parts of unscratched lengths l_1, l_2and such that l_1 = eta l_2 where etais an integer. The corresponding force constant are k_1and k_2, then identify the wrong statements below,

Answer»

FORCE HASTO be kept same to find `k_1 and k_2`
`(K(eta + 1))/(eta) and (eta + 1)`
`(k(eta - 1))/(eta) and (eta + 1)`
`(k(eta + 1))/(eta) and k(eta + 1)`
