Answer:
Spring- mass oscillator Suspend a light pan from the lower end of the spring suspended vertically from a rigid support. Add a suitable mass M in the pan so that the spring is stretched to about triple of the unstretched length under its own weight. Take the position of the pointer as zero. Note the position of the pointer for three values of mass in the pan (m) less than M and three values of m more than M Find the extension (x) in each case. Plot a graph of (m - M) against x. Hence determine the force constant of the spring.
