Question

Two spring mass systeam have equal mass and spring constant `k_(1)` and `k_(2)`. If the maximum velocities in two systeams are equal then ratio of amplitudes of `1st` to that of `2nd` is :
A. `sqrt(k_(1)//k_(2))`
B. `k_(1)//k_(2)`
C. `k_(2)//k_(1)`
D. `sqrt(k_(2)//k_(1))`

Answer 1

Correct Answer - D
`(1)/(2)mv^(2) = (1)/(2)K_(1)x_(1)^(2)`
`(1)/(2)mv^(2) = (1)/(2)K_(2)x_(2)^(2)`
`K_(1)x_(1)^(2) = K_(2)x_(2)^(2)`
`(x_(1))/(x_(2)) = sqrt((K_(2))/(K_(1))`
