Question
Two identical springs of springs constant k are comected in series and parallel as shown in figure Amass M is suspended from them. The ratio of their frequencies of vertical oscillation will be:
Options
A.1 : 2
B.2 : 1
C.4 : 1
D.1 : 4
Solution
We know that
T = 2π
⇒ n = 
for a spring mass system.In case Iif Kis the resultant spring constant,then
Incase II,K = k + k = 2k
If n1 & n2 be frequencies in two case, then
n1 =
n2 = 
⇒ =
