One end of a long metallic wire of length L is tied to the ceiling. The other end is tied to massless spring of spring constant K. A mass m hangs freely from the free end of the spring. The area of cross-section and Young's modulus of the wire are A and Y respectively. If the mass is slightly pulled down and released, it will oscillate with a time period T equal to
Text Solution
Verified by ExpertsThe correct answer is:
B
The wire may be treated as a string for which force constant 
Spring constant of the spring 
Hence spring constant of the combination (series)
Time period
