Answer» Correct Answer - A `k_(1)x_(1)=k_(2)x_(2) =F` `W_(1)=(1)/(2) k_(1)x_(1)^(2) =((k_(1)x_(1))^(2))/(2k_(1)) = (F_(2))/(2k_(1))` Similarly, `W_(2)=(F^(2))/(2k_(1)) rArr W prop (1)/(K)` `W_(1) gt W_(2) rArr k_(1) lt k_(2)` Statement II is true. Now, `W_(1) = (1)/(2) K_(1) X^(2)` `W_(2) = (1)/(2) K_(2) X^(2)` So, `W_(2) gt W_(1)`, Hence, statement `I` is false. |
