Question: Answered & Verified by Expert
A body of mass m is suspended from vertical spring and is set into simple harmonic oscillations of time period T . Next the spring is fixed at one end on a smooth horizontal table and same body is attached at the other end. The body is pulled slightly and then released to produce horizontal oscillations of the spring. The time period of horizontal oscillatioins is

Options:
  • A T
  • B 2T
  • C T2
  • D Infinite as the spring does not oscillate

The correct answer is: T
Time period of spring is given by :

T=2πmk 

Time period of a spring and mass does not depend, on it being horizontal or vertical.
So in both cases, it will be same i.e. T.
