One end of a long metallic wire of length L, area of crosssection A and Young’s modulus Y is tied to the ceiling. The other end is tied to a massless spring of force constant K and a mass ‘m’ is hung from the free end of the spring. If ‘m’ is slightly pulled down and released, then its time period of oscillation is
