Questions
A body of mass m hangs from three springs, each of spring constant ,k as shown in fig. (11). If the mass is slightly displaced and let go, the system will oscillate with the time period
detailed solution
Correct option is B
Equivalent force constant of two springs connected in parallel is 2 k . The other spring is now in series and hence ' the resultant force constant =k×2kk+2k=2k23k=2k3 T=2πm(2k/3)=2π3m2kTalk to our academic expert!
