Q.  
In the spring mass system if the mass of the system is doubled with spring stiffness stiffness halved, the natural frequency of longitudinal vibration


Answer & Explanation

Natural frequency of spring given by,
ωn = √(k/m)
Putting given value, in above equation we can observe that natural frequency get halved.

Thus correct option is: C.
