An extension of 2.5 cm is produced when a mass is hung from the lower end of a light helical spring which is fixed at the top end. and to which Hooke's law may be assumed to apply. If the mass is depressed slightly and then released, show that the vertical vibra- tions executed are simple harmonic and calculate their time period. Ifthe mass of the spring is taken into account, the oscillating mass M may be considered increased to (M + m). Give reasons why wa is less than the actual mass of the spring and describe an experiment in which a series of known masses is used to determine the value of m.
