A mass M is hung from a frictionless, massless pulley. The pulley is suspended by using an inextensible, massless rope of which one end is directly fixed to a support, and the other end is connected to the support through a linear spring of stiffness constant k (see figure). The natural frequency of this system is

- B. √2𝑘 𝑀
- C. √𝑘 𝑀
- D. √𝑘 2𝑀
Answer: A. √4𝑘 𝑀
