Statement-I : For a particle of mass `1kg`, executing `S.H.M.`, if slope of restoring force `vs` displacement graph is `=-1`, then the time period of oscillation with be `6.28s`. Statement-II : If `1kg` mass is replaced by `2 kg` mass and rest of the information remains same as in statement-1, then the time period of oscillation with remain `6.28s`.A. Statement-I is true, Statement-Ii is true, Statement-II is a correct explanation for Statement-I.B. Statement-I is true, Statement-II is true, Statement-II is NOT a correct explanantion for Statement-I.C. Statement-I is true, Statement-II is falseD. Statement-I is false, Statement-II is true |
Answer» Correct Answer - C As `F=- m omega^(2) y rArr` slope of `F -y` graph is `-m omega^(2) - 1 =- m omega^(2) =- omega^(2) =- omega^(2) rArr omega =1 T = 2pi = 6.28 s` If mass is changed but slope remains same, the time period will change. |
